Customer Questions


I'm not clear on one of the topic, but isn't OEM a genuine factory part? So is this part made from Honda/Acura factory OEM?


Yes OEM and Geniune are used interchangeably a lot of times. This is a GENUINE part, meaning it comes straight from Acura. Read more on this topic here: What is the difference between OE, Genuine, OEM, and OER/Aftermarket Parts?

Q:Can I use this throttle body with an RBC intake manifold without an adapter?

Yes this should bolt up fine to an RBC intake manifold.

Q:Will the OEM intake hose on the 04-05 TSX fit over the inlet side of the throttle body? Also are any special gaskets needed for use of this on the 04-05 OEM intake manifold?

The throttle body is larger than stock but not exceedingly so. We believe it is possible to stretch or modify the stock intake arm to fit over.

Q:Will this work on a 2004 honda accord v6
A:Yes you could use this on a 7g Accord V6
