I will probably get the 6637 filter soon and JUNK the K & N I've got. Just have a question......I know the 6637 is a dry open air filter. How many of you use a pre-filter on it......and is it homemade or is it available to buy for it? I ask because of major snow here and wet roads....just seems like a bad combination for a dry open-air filter! Thanks in advance......

 

I run a pre filter and a member here make them, They are awesome. Search under pre filter you should find answers to your questions.

 

F250_ makes them for us..here is a link to his filter cover... shoot him a PM... and he will set you up....

I run an Outerwears pre-filter on my 6637, its water repellent and washable. I ordered it "open" on both ends so I could mount my filter minder and air temp sensor in the end of the filter.

 

I made my own. I had someone teach me how to sew and I made a pattern out of newspaper. Pretty simple once you get into a rythem sewing.

 

ordered the 6637 this morning from fleetfilter.com & I CAN'T WAIT to see the difference!!!!

 

I have a couple of Pete's filter covers. They fit and look great.


Great guy to deal with.

 

I already messaged him about it

 

how much was the filter if you dont mind.Here in hawaii it is 56.00 bucks.

 

filter was $27.33 and with taxed shipped was $35.76. I called the local Napa store here and they wanted $49.95....a penny saved is a penny spent on another mod!

 

I just used a piece of panty hose - seems to be working well.

 

I hope it isn't FISHNET style!!!

 

LOL - they tend to stop the wasps and hornets :-)

 

And carps and bass.

Mine was made out of some blue mesh material, like (shorts you would were to play basketball in).
