Replacement air filter for GTX/SLP airbox

**99gtxws6** · 06-19-2010

Anyone know off hand what filter I need to replace the K&N cone in my GTX?

I know places sell the whole SLP airbox assembly, but I just need the filter replaced. This old one has had it.

The number on the open end of the filter, where it connects onto the air box lid, is F035A4 but I can't match that up to anything K&N has.

here is what you need to do:

go to K&N website and look for their catalog. Somewhere in that catalog or on their site, there should also be a diagram to show what part of the filter is the base and stuff like that so you know how to look at dimensions. Take a ruler and measure your filter, then find a filter with those dimensions. Once you find the part number, you can find it online somewhere to buy.

nevermind. i went and found the link for you. At the top is the diagram, then it has dimensions of each filter. You also want a filter with a rubber "top style". Pretty sure the slp type filter is either 7" or 9" in length....

I appreciate it. I was just hoping someone already had a part number for me, or a link to a replacement, so I could be lazy and not have to take my airbox apart...LOL

And I know it's not a 9" cone filter. I've got one here and it's too long for the airbox. 7" would probably work, just need to measure the inlet size and match it up.

all the slp box is a stock airbox modified to be able to run the fresh air vent from the hood to the box it should be a stock filter number which should cross reference to a KN filter

Mines got a cone filter in the box...

SLP intakes used a 7" cone filter. They used K&N's before going to the blackwing filters.

Yeah, the slp box I have uses a cone filter, not the stock style flat filter.

I'll use either one, a K&N or blackwing, you happen to have a part number for the blackwing filter? Or know where I can pick one up?
