i just bought a k&n drop in filter replacement thing, was it worth the $50 i just spent? i dont expect the truck to pop a wheelie or anything but on a dyno would the filter actually help any? and do they improve gas mileage?

im looking for little engine mods to give my truck some more go, any ideas? i tried the jet chip and that didnt help at all! i have a flowmaster muffler and i will put the k&n in the morning. some of my mustang driving friends put different size pully's on the 5.0's and they said that helps (i dont see how)

 

I have notice 1.5 to 2 mpg better with my K&N drop in I put on this week.

that your chopper?
specs?

 

What engine do you have in your truck? I've put K&N drop-in filters in all of my Dodge vehicles. I noticed improvements on my 8.0L 2500, Viper and 5.9 R/T Durango. I've also heard that it does nothing for the highly computerized HEMI. I bought one for my '04 1500 HEMI already and plan on dropping it in this weekend.

I have the K&N seens about a 1.3 mpg on avg(atleast thats what the computer says) Over time it weill pay for itself i guess. What the stanger's are talking about are "performance Pulleys". They are smaller, intheory they slow down the accessories so that they dont steal as much power. Its fine for normal driving, but if you tow you can run into probs with cooling as the fan and the waterpump are turning slower.

Yes it's a bell 206L3

 

K&N is worth the money even if it doesn't give you any extra power or mileage. Just the fact that it filters better and is reusable should be enough IMO.

 

dave,
have you poppped in the k&n in the hemi yet. would love some input was thinking about getting it but heard the same thing about no gains for the hemi. as far as the reuseable/better filter, if thats all i get outta thge deal, they dont get my $, imo

 

No arguement with the fact that a K&N or any other claimed High Performance Air Filter will offer less restriction, however, and this is based on my experience only, use of a less restrictive air filter can induce more contaminants into the engine. I have owned both a Cummins and a Powerstroke and performed oil analysis routinely on both. Upon switching to a K&N air filter I noticed an increase in the silica content on the following analysis. That was using the factory oiled filter. I removed the filter, cleaned and re-oiled. The following analysis again indicated an elevated silica content. I switched back to the stock type filter (WIX brand) and the following analysis indicated a drop in silica content back to the number prior to the K&N swap. Not saying that K&N or any other high performance filters are bad. They do what they claim and that is increase air flow performance. For the long haul, I will stick with stock design filters. Weekend racing, K&N or whatever brand all the way.

 

I would tend to agree with RAM04 on K&N filters. I see alot of "subjective" evidence that K&N filters help, but I have yet to see anything in writing that I can believe. I tried a K&N in a 2000 Ranger and never saw anything in performanceor mileage increase that justified the $50+ cost. Perhaps, I am wrong, but seeing is believing.
