I installed my injen sri last week but ive been getting some vibrating feel in my clutch,brake,gas pedal it wasent there before i installed it. I also put it in once then took it out to change a coolant hose on it after that 2cd time i changed it this vibrating feel started to happen in the pedals. It run's fine other then this highway speeds are smooth. redline running is smooth but its only at slow speeds i get this someone mentioned that the intake is prob hitting or rubbing the master cynlinder. I dont where the master cynlinder is if somone can post a pic or has had a similar issue please let me kno thanks in advanced.

 

Master brake cylinder? It's mounted in front of that big black doughnut high on the driver's side firewall. It also has the brake fluid reseviour on top of it. Look in your owner's manual. There is a picture of it in there under the section dealing with brake fluid level.

 

or maybe... its just resonating more than stock and the sound is causing the vibrations at low revs which are more noticeable than rapid vibrations.

 

Well is the master clutch cynlinder, brake cynlinder located close together.

 

I gave you a pic on your SRI thread.

 

Does your's do it i dont see a reason why it would do it ive seen another fellow si owner's injen sri installed and it looked the same. I got a response from a previous post with someone saying it happens all the time and they put foam there or etc i will have to dig up that post.
