Customer Feedback

Just installed the short ram intake on my 03 Chevrolet Cavalier and I'll admit I was skeptical about the performance upgrade I would recieve from this part.  After driving it, I was amazed with the throttle response and sound that the new intake gave my car.  I would recommend to anyone, young or old, that wants more out of their Cavalier to install (very easy installation) this intake on their ride.  Thanks to k and n for making another great product and letting me enjoy driving much much more!!

To everyone at K&N,
     I recently purchased and installed a K&N typhoon kit for my 2003 Chevrolet Cavalier.  The vehicle has the Ecotec engine new to GM's small car line.  The installation was a breeze.  The instructions you sent me, truly made this a one hour job. (very easy, and fun) The fit and finish of the Typhoon kit was perfect, everything laid right into place with ease, and was very well designed.  While shopping for my intake, I noticed that K&N was the only company that included a Manual transmission clutch reservoir relocation bracket in the kit. (because my car's reservoir was built onto the stock airbox that was replaced by the Typhoon kit)  Other intake brands charged extra for this piece.  To make a long story short, the intake showed a 6hp gain to the wheels on my vehicle, which is a 2.2l four cyl. with 140hp stock.  This gain can be felt at the mid to top end of the rpm range.  Another great thing about this intake, is that it remains quiet, and inaudible in tone, and then gives a great sound at wide open throttle.  So you don't constantly have to hear the tone of the intake, until you're ready to use it.  All in all I found this intake kit to be well worth the money and I would install one on other cars in the future!  Keep making a quality product for Sport Compacts and I will keep buying them!

Thanks K&N!

Great Product - I want to sincerely recommend your air filters to everybody. I put one on my 1991 Chevrolet Cavalier. The difference was immediate: 1) More power and acceleration, 2) it went from 35 MPG to 39 MPG on the highway, amazing!!
