i noticed the other night that my engine is making a knocking noise.. but its weird because when i start it up it doesnt make that knocking noise until the engine's completely warmed up after 5mins... also there's been a buzzing sound coming from my dashboard when im at WOT its gets pretty loud at 4k-5k.. notice i only have injen CAI, AW header, magnaflow resonator and TRD exhaust.. can someone tell me what's the knocking and buzzing sound before my car blows?!?

 

Try a different gas station. The buzz is probably your intake touching the frame of the engine bay, try putting a rubber lining on the frame where the cool air piece dips down. These are suggestions, nothing that I'm sure about though.

 

yea i already have the rubber lining on the metal part the might hit the intake.. thanks for the suggestion.. im more worried about the knockin in my engine though..
