I needed a new filter bad for my intake, because it was so dirty it didn't even come clean when I cleaned it. For the same price as a stock one, I got a larger filter that should stay cleaner longer and flow more air when dirty. You can see in the pic the size difference, and what my old one looked like. BTW, I ran my 14.4@98mph on that dirty filter right there. I might pick up a tenth from the new one...lol.

 

here it is installed, with plenty of room still.

 

I need a new filter too... i'm not sure about the sizes tho. I'm guessin w/ new filters, we'll need a new adapter?

btw, did you make your own heatshield? i'm thinking of doin it.. not sure what material to use tho.

 

No, I bought one specifically to fit the 6 inch opening of the JWT venturi adapter. Yeah, my ghetto heat shield is a plastic roof vent from Lowe's. Works great.

 

How long does it take to recharge my k&n?

 

drying it out is what makes it take so long...

i've recharged my filter but it did no good... or i did'nt apply the oil right. whatever it is, my filter still looks like crap and it's time it needs replacement after like 100k+ miles lol

 

you put 100k on one air filter??????? Should I just replace my k&n with a new one?

 

Hey, I was wondering what the part number for the new filter is.

TIA

 

Better yet where did you buy the filter? I probably need one before too long, and out of all the mods out there I never see replacement filters.
-hype

 

first you go to this website and find the exact size that you need. It shows you how to measure.

Then I ordered my filter from here, just type in the part number you need.

The one that I got was part number RF-1013. Hope this helps.

 

does that filter have a closed end or is it a dual cone design?

 

does the filter make your intake any louder? it being a bigger filter, more air flows in, more air more noise?

 

they do not list a 1013. they list a 1010 that is 4" long and a 1017 that is 8" long.

 

nevermind I found it

 

It is a closed end. I don't really like the inverted cone design, because I think it causes turbulence in the intake. The JWT adapter is a venturi cone, which works great at getting the air in smoothly.

 

I didn't really notice a difference in sound. The engine can only flow the same amount of air, regardless of filter size. The other filter was big enough for the engine, I just got a larger one to flow more air longer when its dirty. If anything it sounds more refined at high rpm.

 

I forgot to mention that my gas mileage has gone up dramatically, so I know that the filter was in bad shape. I can't wait to go back to the track now. I just wish there was still cool weather.

 

Hmmmm...i tried to find a replacement for the JWT before and did all the measurements and none of the ones from K&N seemed to work. Well, I'll try the one you got, by any chance how much you pay for yours? Thanks.

 

the price is on the site I listed above, I think it was like $45 or something with $5 shipping.

 

those stainless steel air filters work the best in my opinion, never need recharging blah blah lol

 

accoirding to this, stainless steel sucks a nut for filtering.

 

i had mine on my 240 for 55000 miles and had no issues at all, so im stickin with it for the max
