Wow ... big change on my K&N

[Vipermann]

Per the earlier posts, my car was running sick with the K&N set up. So I drilled out the vacume hose connections to match the stock sizes... what a difference! And the whistle sound is gone too. I disconnected the battery to reset the controller.

BTW, where is the controller located? Is it hard to change if I got the Mopar Race controller?

Vipermann -

I have the K&Ns but have not noticed the problem. Thinking about doing the mod anyway.

I did not understand from the last posts exactly what needed to be drilled. Sorry - I am partially mechanically illeterate.

Did you actually drill the K&N plastic where the vacuum hoses hooked up?

thanks in advance -

Yes you drill the plastic fittings for the hoses ... look at the stock unit for the correct size.

thanks!!

Wasn't this a problem on the earlier version K&N kit? Not at all on the new ones in the last 6 months.

It is the inside diameter of the PCV and the idle air fittings that you need to increase to the stock diameter.

The controller is under the hood, just behind the radiator on the drivers side. the upper radiator hose hides it pretty well.

Can someone tell me the exactly diameter or drill bit size to use? I dont have my original pipe handy.

Been a while. Check the archives from last summer and you will find the answer.

I used a 1/2" bit on the larger hole, and a 1/4" bit on the smaller hole.

The problem is solved as far as the bad running of the engine. As discused before one need to remove the baffle and then remove the K & N filter assembly and clean any oil from inside the throttle body. Also remove and clean the two sensors with electric motor cleaner and air dry. I looked at mine and found that the two hose connections were much smaller than the stock, my unit was the lster design i was told, so I drilled them out to the same size as the stock unit. The stock air box does not come even close to fitting tight around the K & N plastic T assembly so I would suggest putting foam tape around it between the air filter box and the T connector, make sure you check mit with a flashlight as there is a ton of room between the two. Next one needs to remove the factory baffle from the ram air duct in the hood and again use foam tape to seal between the air box and the hood so no outside air enters except throuh the hood scoop. Be sure to disconnect the negitive battery post, 10 mm socket, and leave it off for a few minutes so that the computer is reset. This made a whole world of difference on my viper. MAKE SURE YOU HAVE YOUR KEYS IN YOUR POCKET BEFORE DISCONNECTING THE NEGITIVE BATTERY BECOUSE WHEN YOU REATTACH THE BATTERY CABLE THE WHOLE SYSTEM GOES INTO ANTI-THEIF MODE AND SHUTS DOWN. JUST OPEN THE DOOR WITH YOUR KEY, UNDER THE SIDE SCOOPS ON THE DRIVER DOOR IS A KEEY LOCK, AND GET IN AND START THE CAR AND LET IDLE FOR 10 MIN AND EVERYTHING WILL WORK AS IT DID BEFORE
