...so, how is it done?

Is it better to just get a new filter?

I got about 25k on it already, and it's filthy...

 

from what i remember the filter that LMS gives you is a K&N filter. you can either buy a new filter or you can buy the filter cleaning kit K&N offers

 

Click here for cleaning instructions using K&N's (or anyone else's, for that matter) cleaning kit.

I say buy a dry filter from AEM No oil means no worries about the MAF getting messed up!

 

The Fujita filter can be run as a dry filter as well.

So, does anyone know which K&N filter to buy if I just want to replace it?

 

The K&N filter for their IS350 intake is part #RU-4990, which has a 3" diameter opening, and is probably the one LMS uses. Measure the diameter of your LMS intake tube and compare it to make sure it's the same size. If it's not, then you can find one of a different size here.

I put around 8k miles on the filter for my LMS before I cleaned it out. No need to buy a new one, just buy the k&n filter cleaner they sell at Pep Boy's, or Autozone & follow the instructions. Peace a Cake, & It in fact does work well. Save's you around 25-30$ on a new one.

 

Just be careful not to over oil it after you clean it!!

 

I purchased the LMS intake (with K&N filter) in December 2005. I have since been using the AEM dry filter and have not noticed any performance changes. I rotate between the two filters every 7,500 miles. I know that this maybe overkill, but I want to obtain better MPG performance.
