Details

This intake manifold spacer is an evolution of the popular MDX Manifold Spacer Mod performed by grassroots enthusiasts since 2009. With a larger spacer in the intake manifold, increases in torque can be found in the lower RPM range without any compromise in upper RPM flow.

The MDX mod provided great power increases but came with a compromise. The spacer moved the intake manifold up almost 1.75" and cause clearance issues with the hood, intake system fitment concerns, and the need for other plumbing and/or electrical re-routing. Many users installed hood spacers to give more clearance between the hood and the engine. Also, longer hardware was needed to install the spacer and sourcing quality hardware from Acura proved difficult due to persistent and lengthy backorders.

P2R Intake Manifold Spacer will increase torque in much the same way as the MDX spacer did, but eliminates the compromise. This spacer is made from 6061 aluminum. Combined with 2 P2R Thermal Intake Manifold gaskets your total spacer thickness would be 1". The spacer kit itself includes necessary bolts and washers to install so the hardware concern of the past is non-existent (no gasket is included).

There is a reusable metal gasket in the stock manifold assembly, so to install this part one additional gasket is needed. Please see the option above for added a gasket to your order. We recommend the P2R thermal gasket, which helps prevent heat transfer from the engine to the manifold. The cooler manifold will help promote greater air density in the engine and also provides additional power due to its thickness.

Oftentimes people will select a second P2R gasket because it will add a little more thickness to the overall stack, providing more overall manifold volume gain. It does not provide additional thermal blocking, necessarily. Just a little more spacing.

Customer Questions

Q:

Hi I have a question in regards to the pr2 intake manifold spacer for the j series does it fit a 2004 accord v6, in the top next to the price says except for the j 30 and in the fitment says 2003-12 accord it\'s confusing can you give more info if it fits my accord 2004 j30

A:

Hello, yes it does fir the J30 in the 2003+ Accord V6. We have clarified the listing to state which J30 engines it does not fit.

Q:

Does this clear the hood and work properly on a 2003 acura tl type s?

A:

With this spacer the manifold is moved up in position on the engine. This P2R spacer is designed not to raise the maniflod so high as to cause a hood-clearance issue.

Note that while this part may be used on an early multi-port head J-series, it is intended for use on newer, single-port head engines.

Q:

Will this fit for 2012 Honda odyssey?

A:

Yes! It will fit the J35A7 engine in your Odyssey.

Q:

I see that it fits the Accord up to 2012, but will it fit the 13 Accord J35Y?

A:

Yes, we have listed this part as fitting all single exhaust-port head J-series. That is every J-series engine after the 2nd gen TL/CL or 6tth gen Accord (98-02).

Q:

would this fit a 04 tl j32a3 engine with a j37 intake manifold?

A:

Yes this fits on all single-port J-series manifolds.

Q:

When I get this product, will it have the longer screws to bolt straight up or have to order it for the dealer and do all sell hood spacers

A:

The longer hardware you need is included with the kit. You will not need hood spacers to fit the spacer, either.

Q:

will is clear the hood of a 2008 accord?

A:

Yes, it will.

Q:

Would this fit a 2007 TL Type S?

A:

Yes it will. All single exhaust port J-series engines can use this part, including the J35A8 in your TL-S.

Q:What modification needs to be done to fit this on a J32A1?
A:

This part we believe fits on the J32A1 however the EGR port is not going to line up right. It may be able to be used ok, but it is not designed for this application.

Q:Can I attach an AEM V2 CAI to either the stock intake manifold or J37 intake manifold with this spacer installed on a 2003 Accord J30A4?
A:

Yes you can. Although some adjustment of the couplers will be needed. You may need a new HPS coupler if you are looking to install a J37 throttle body as well.

Q:How does this mod affect top end hp vs. Bottom power?
A:

Thie intake manifold spacer provides power in a broad powerband range, not just high or low. You'll feel the power more in part-throttle and roll-on throttle situations than strictly WOT.

Q:Will this fit and clear the good on a 07 tl s?
A:

Yes this part fits on the J35 in the TL-S, and you will not have hood clearance issues, either.

Q:Will this clear the hood of a 2014 Accord v6 j35y?
A:

Yes, it will. These spacers are designed not to have hood interference on Honda and Acura sedans.

Q:Will this spacer cause a problem with the mounting or my short ram intake? It seem that if the manifold is raised 1" then the brackets for the intake pipe will not be long enough.
A:

While the throttle body position will move, most all intakes are able to be adjusted or re-positioned in order to fit with the spacer in place. You should not have an issue.

Q:Will this fit a 2013 SH-AWD? If not what is the best option for this car?
A:

Yes this spacer will fit basically all J-series Honda V6 engines, including the one in your SH-AWD vehicle.

Q:Would you recommend this to someone with a '04 TL auto with supercharger (can't tune)?
A:

Because this part spaces up the manifold it may not be possible to install this part on a supercharged TL. This is because the outlet from the blower rigidly mounts to the inlet on the manifold and spacing the manifold up would misalign the blower outlet.

Q:Would you recommend this to someone with a '04 TL auto (no tune) with a supercharger and ATLP J-pipe and exhaust?
A:

Because this part spaces out the throttle body it may not be possible to install this part on a supercharged TL. This is because the outlet from the blower rigidly mounts to the inlet on the manifold and spacing the manifold inlet misalign the blower outlet. It may be installed between the blower inlet and the throttle body, but this would make the intake fitment rather tight. We feel there would be very limited benefit in having this part on a supercharged TL anyway.

Q:Will this fit and clear the hood of a 2003 CL Type S with a j37 intake manifold and AEM CAI?
A:

We believe the size of the P2R spacer is not too much and will allow fitment on your application.

Q:will it fit honda odyssey 2006?
A:

Yes it should fit your Odyssey engine perfectly fine.

Q:Will this work on a 03 CL Type S and clear hood?
A:

Yes this spacer will improve power and should not cause interference with the hood in your CL.

Q:I was trying to confirm fitment for a 2013 Accord V6. I see only up to 2012 is listed but i noticed it fits the Acura J series variants of 2013-2014
A:

The data on the page was old, we have now updated it to include 13-17 Accords.

Q:I am planning on getting the HTSpec J37 Magnesium Intake Manifold & Throttle Body Kit, Honda J-Series V6, for my UA7 TL (which has the option of thermal gaskets for the TB and Manifold) along with this kit, in that case do i need to purchase this manifold spacer with 2 thermal gaskets or just 1? Thanks in advance.
A:

Purchase the spacer with one gasket, and the manifold with one as well, providing you two total.

Q:I have a 2011 accord v6, how many of these spacers do I need?
A:

One, and at least one extra gasket.

Q:WILL YOU NEED 1 OR 2 THERMAL GASKETS WITH A J32A3, WITH A MDX INTAKE MANIFOLD AND J35 (2012 HONDA ODYSSEY) RUNNERS?
A:

You will need two gaskets in all but usually you can reuse the stock MLS gasket on the engine, requiring you to buy just one with the spacer.

Q:Are the gaskets necessary to install this or not?
A:

With this spacer you can reuse the factory steel gasket but one additional gasket is needed for the opposite side of the spacer.

Q:Will this fit for 2013 Honda Pilot on J35Z4?
A:

Yes it will.

Q:i have a 3.5 out of an 03 odyssey the tras off this motor is already in my 03 acura tl s type with the 3.2.will the 3.5 tit in my car
A:

Yes, this part will fit on the J35 from the Odyssey.

Q:will this work on a J35a4 odyssey?
A:Yes, although your engine already has a large spacer under the manifold so we would not recommend installing this one unless you planned on taking the other one out.
Q:Are the thermal gaskets reusable if I need to remove the upper intake manifold for any reason after they are installed? Or are they a one time use gasket?
A:Most of the time yes they are reusable. We have only seen them leak in very rare cases. We would suggest that you remove and inspect them and make sure to install them in the same orientation as the initial install to properly reuse them.
Q:Will the bolts be too long if two oem gaskets are used, as opposed to the thermal gasket?
A:

Not at all, the longer bolts with this kit will work with both the stock and the thicker P2R gaskets.

Q:Sorry might be a dumb question but why does it give you the option to buy 2 thermal gaskets? Am I missing something.
A:

Oftentimes people will select a second P2R gasket because it will add a little more thickness to the overall stack, providing more overall manifold volume gain. It does not provide additional thermal blocking, necessarily. Just a little more spacing.

Q:Hello can ne fit on j35a9
A:Yes, it will fit your engine.
Q:will this fit on a J35Z2 on a 2008 honda accord exl ? will i have any hood clearance problem?
A:Yes this part will fit on your Accord's J35 engine and you would not have hood clearance issues with it.
Q: With this fit a 2003 Acura CL type S
A:No, your CL has a Gen 1 J-series.

  • Amazing Performance Mod April, 13
    By Sri, Street Performance Enthusiast
    Purchased this to go along with my J37 Intake and Throttle Body swap. I installed this on a 2010 Accord V6 and the difference was very noticeable. The car feels much more responsive and the power gain is amazing. The P2R spacer fits in nicely and leaves enough room to close the hood. The package comes with 7 13mm bolts, and 2 allen head bolts. The 2 allen head bolts replace the original factory studs that help to center the manifold. When installing this make sure to center the manifold and gaskets to avoid any air leaks. Also be sure to get a small size torque wrench to torque it to the correct amount.(16 lb-ft)
  • more torque January, 3
    By albert stubblefiled, Spirited/Stylish Commuter
    My wife bought me the p2r manifold spacer for my 05 acura rl. I don't really have a multitude of options for modding this ride. I saw this one a while back and mentioned to her that I think i would like to get this, but never did. N e way... Got it for Christmas. Took about 30 min to install. And when I got on the freeway ramp, I was wowed. My first impression and every other impression is that I can't believe this is the same car. More torque is more torque. This is not in my head. I haven't felt this with any of the other mods iv'e done. Amazing and simple. much needed on any J-series

    By Antonio Rodriguez, Grocery Getter
    Fit perfect and work as great as specified. More torque at low rev. The installation was a breeze and you will notice the difference before and after the installation. Bring more mod for MDX 2010. Thanks
