keebler85 Posted March 20, 2008 Report Share Posted March 20, 2008 I have a K&N intake that had the original filter on it...i just bought a RC-5139 for it and the new filter is about twice the size of the one that came with it...will this make my truck run lean? i will post pics with the difference showing to help out Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted March 20, 2008 Report Share Posted March 20, 2008 Here are the proper replacement filters for the K&N FIPK on a 2003 SSS...... 57 Series - RF-1042 77 Series - RC-5046 I don't see how a larger filter would you make you run lean, post some pics of the size difference.

And where did you get that part number from? Quote Link to comment Share on other sites More sharing options...
keebler85 Posted March 20, 2008 Author Report Share Posted March 20, 2008 my old one had rubbed a hole in the bottom a little from a bracket that i did not see and i didnt want a filter with a hole in it....it looks funny when you open the hood and see how huge the filter is .. its a RC 5139...

sonickoolten Posted March 22, 2008 Report Share Posted March 22, 2008 that ish is huge what do u mean lean? will it run better? Quote Link to comment Share on other sites More sharing options...
Badkarma Posted March 22, 2008 Report Share Posted March 22, 2008 The only diffrence is the filter as more surface area. It will not make your truck run lean. Quote Link to comment Share on other sites More sharing options...
