K&N 57-1508 - K&N 57 Series FIPK Air Intake (50-State Legal) - FREE SHIPPING!
ORDERED AND RECEIVED THE KIT FOR MY VIPER, HAD IT INSTALLED BY MY MECHANIC. BELIEVE COULD HAVE DONE SO MYSELF BUT THERE WAS A LARGE ORANGE PRINTED SHEET INCLUDED RE POSSIBLE DISASTROUS CONSEQUENCES IF INSTALLED INCORRECTLY. HAD TO HALT INSTALLATION PROCESS BECAUSE ONE ADAPTER WAS MISSING; CALLED THE SELLER AND THEY FED-XED TO ME OVERNIGHT. I WAS GIVEN PAUSE INITIALLY BECAUSE A FRIEND INSTALLED ONE ON HIS LATE MODEL CORVETTE WITH THE RESULT THAT SOME SORT OF AIR FLOW MONITORING SYSTEM WAS ADVERSELY AFFECTED BY THE KIT AND HE RECOMMENDED THAT I DO NOT INSTALL.WITH MANY YEARS GOOD EXPERIENCE WITH K&N, I WENT AHEAD AND THUS FAR I HAVE HAD NO PROBLEMS. THE KIT INCLUDED A DYNO TEST FOR THE MODEL YEAR OF MY VIPER INDICATING I WOULD PICK UP ABOUT FOURTEEN HORSEPOWER AND I AM WILLING TO SAY THAT THIS IS PROBABLY TRUE ALTHOUGH A BIT DIFFICULT TO CATEGORICALLY VERIFY BECAUSE A 14 HP INCREASE WOULD REPRESENT SOMETHING LIKE 2-3%. UNDER STIFF ACCELERATION THOUGH, YOU CAN CLEARLY HEAR SOUND OF FREER FLOWING AIR MOVING THROUGH THE TWIN K&N FILTERS. I AM HAPPY WITH THIS PURCHASE.
Overall, the intake is nice. It did require some modifying to mount it. But it was easy to install. Im not sure if i notice a difference, but at least the engine compartment looks cleaner.
