Hey orggers, i need some advice...Its a K&n air filter RU-2820
http://cgi.ebay.com/ebaymotors/K-N-R...QQcmdZViewItem

 

you need a maf adapter

 

it will fit but you will need the maf adapter just like paint said

 

right, i have the mid-pipe and couplers. I am replacing my ebay(crap filter) with this one...

 

yup that was the same filter i used on a 3" maf adapter (didnt buy it off ebay tho).

 

look further down on the page....

"You are bidding on a Brand new in the Box
K&N RF-1041 7.5 inch tapered Universal Air Filter
(RF-1041)"

and go here: knfilters.com RF-1041

i think the filter you are buying is different than the item title

 

man u got good eyes, now why would they put two different model numbers on there.. where did u buy urs at? got pics of it installed?

 

i dont think it will fit, but you can still try

 

I had that filter on my max, the one in the picture on the auction not the other model number one. Fits fine i didnt have a problem.
