Just put in new intakes: k&n typhoons
When I start it, it makes a rumble noise and shakes the brake pedal a bit don't know if it cause it's taking in air or what?
Also in reverse it does the samething other then that it's perfect just wanted to know if it's something outta the ordinary. I searched on this topic no answers.

 

Did you reset the ECU?

 

No I haven't I'll do that now
I know there's two ways pedal and removing battery?

 

I would check for leaks. An intake should not do anything abnormal.

 

I had a rumbling issue coming from the engine bay when I installed my R2C's. Don't think it affected the brakes though..but Check the bolt that secures the intake to the "frame" The oem bolt turns out to be a bit too lot for the R2Cs and it had excess clearance on the bottom that kept hitting a piece of metal when the engine idles and in motion (mostly around 2k rpm)
