Review on HPS 87 68426 RED 4 Silicone Intake Hose by Ron Houston

So, to agree with everyone who mentioned trimming, yes the passenger side should be trimmed about 1/2 inch. I recommend removing the front engine cover to make it easier, as well as the brace. As for the effects of the part. When it comes to the sound I can say there isn't one outside of the car but as soon as you start moving you can hear the difference and it sounds better and a bit louder especially when you crank it up. Well, when it comes to performance, the dyno seems to have grown quite a bit, but I attribute that to the fact that the car responds better to the accelerator. What I call the heavy accelerator pedal is gone. So the fact that you replaced a stock tube with poor aerodynamics with one with poor aerodynamics makes a difference. If you remove the muffler on the driver's side, the sound in the car will be clearer. So get the K&N filters as a set for extra driving fun.
