The benefits are better air flow to the intake for a slight gain in HP.

Easy to install, I choose blue tubes, but instead of fixing them in with the jubilee clips supplied with them, I retained the sprung OE clamps (neater, original kit, and quicker to take on / off). Was worried that the OE clips may move...as on the OE ribbed hoses there are ridges that locate the clamps and stop any migration, but my OE clamps on smooth hoses are holding fast, fine! Expect to here more of a sucking vacuum noise at the front of your Viper when it's running, and especially if you blip the throttle. Maybe a little more throttle responsive, but I can't really say I noticed the extra 10 bhp, but nice to know it's there (dyno confirmed!) You should get a little colorful K&N sticker supplied with the filters to adorn your engine bay. Enjoy...

I noticed a little more sound when I added smooth tubes and K&N. Then I replaced the rear muffler with straight pipes and now it sounds much better.

RWHP 425 after these two mods.
