Has anyone installed the K&N intake for Gen 4?

[VIPER GTSR 91]

Have K&N drop in filter on Gen 4 for 6 months.Works great,no problems at all.I will get one for the ZR1 when K&N put one out.

Same here. 6 months on the Gen 4 and works great. I believe it was only 55.00 and free shipping.

Well I did it, installed it and we will see what happens it was a easy install and have all stock parts so I can go back if needed.

2 whp less at peak, and 6 whp less in the mid range. car ran richer by 0.3 (11.2 stock Vs 10.9 K&N)
I dynod the viper 3 times, got same power # (531 and 530), installed the filter while on the dyno, took 3 min, the car cooled down more then it did between the first runs, ran it again 2 more times, got the 2 whp lower and 6-8 whp in the mid range (528s).

The car ran richer, so it will have to lose power on an NA engine i guess.

I did leave it on.... will drive the car around some and try again. as i did not give the ECU any time to re-learn, not even sure if it will make a difference. We will see..

How can you not gain anything..just hold both up to the light..the KN looks like it flows so much more. And seems less restrictive
