The J's racing strut will not fit with the K&N FIPK. Can someone prove me wrong, if so please explain how you got it to fit.

 

You must be right.

 

Never tried it but the Comptech bar fits. If its shape is like the Comptech it should be raised on one side not perfectly flat. If thats the case make sure that the raised section is on the right side of the car (if you are looking at the car from front to rear )
