I swapped a JDM TurboII engine into my USDM FC3S. Now I am having problems with the intake. The stock airbox from the USDM TII is too small to fit over the mass air flow sensor from the JDM engine. I need to find a stock air box from a JDM TII to fit over it, or an aftermarket replacement filter that is not ricey, and properly fits over the mass air flow sensor. Can any please direct me to where I can find one of those?

 

K&N bolt on kit.

 

what year is the motor?

 

i have a stock TII airbox off my JDM FC if your interested i can ship it to you....

PM me....

 

Its an S5 JDM motor.

 

I can only find the K&N bolt on kit for the S4 RX-7s. The only products for S5 RX-7s I can find on the website is the stock airbox filter, and the oil filter.
