J35 Throttle Body Kit for the 06-11 Honda Civic Si / RBC Manifold

J35 Enlarged Throttle body & Adapter kit, this oversized throttle body kit from HARDmotion allows your 06-11 Honda Civic Si to easily and affordably upgrade the oem throttle body to a larger inlet. Thus allowing more air inside the motor more efficiently and youll gain throttle response and power along the way. This modification is especially good once the car has a modified intake as well as header and exhaust system. By removing the more restrictive stock throttle body and going with this unit, youll get better power and response. This item easily bolts-on and everything is included. No port matching necessary for the install since the size isnt surpassing the manifold inlet size. We then use a High Density Thermal gasket that is built to not only adapt the throttle body to your manifold, but also cut out the extra heat transfer from the throttle body to the manifold and vice a versa. This allows you to reduce some of the coolant and heat paths that can accumulate in the intake pathway (manifold / throttle body). It is also very durable and reusable making it a good purchase overall for anyone who doesnt want to worry about torn organic gaskets from Honda.
