2007 Mustang GT, JLT Air Filter Question

1174 Views 14 Replies 8 Participants Last post by  Thereaper
Quick question. How often should I change the filter and when I change it is there a particular kind that I should get? The only reason I ask is because I brought the car into the dealer for 15,000 mile service and when I took the CAI off it was dirty. Not terribly, but getting there. Thanks in advance.

Change it??? You mean clean it, right?? Get a K&N cleaning/reoiling kit from Autozone. Every 15-20k seems to be pretty good unless you're in a really dusty area.
This is why I ask these questions haha. So these things never need to be changed just cleaned?

That's the general idea. I would recommend you pick up a spare 4" x 9" cone filter so you don't have to worry about downtime when you clean it.
An AEM Dryflow filter is another option. No oiling required. Just wash and dry. I have one oiled filter and one of these.
the upside to having a dry filter is that you don't need to worry about over oiling or under oiling your filter.

That, plus the flow a little better and actually filter better too.
The filter JLT uses is made by S&B filters. You can buy a cleaning/reoiling kit from their website (S&B Filters) for $15. The nice thing about their kit is you measure out the required amount of oil for your filter to avoid over oiling. You can also get the oil in blue if you want another option than red.

Stl, , Do you use the dry filter just until the oiled one sets up?
Just curious.

I mostly use the dryflow.
Are those dryflow filters universal. That is, does the same size fit JLT, K and N, C and L, etc?

In most cases yes. You really need to measure your oiled filter length and opening diameter to be sure. Check the bottom of this page for part numbers and sizing. AEM - What is DRYFLOW?
I use the Dryflow filter for my JLT... The only thing I don't like about it is the ugly white color.

That's odd... Mine's blue.
My AEM is blue also.
