Anyone know what the model #s are for the filters for the Stillen Gen 3's? (K&N and AEM) Thinking about picking up a spare when I clean them.

K&N RU-2820

thanks, but these look to be bigger and cylinder shaped while the ones that came with the gen 3s are slightly cone shaped. the flange looks to be the right size though.

K&N RU-4990 or AEM 21203DK

Thanks. But that doesn't look like the K&N filter I have or the one in the pictures of the intakes. Can you double-check that this is correct?

The RU-2820 looks like the round straight filters for the 370z.

I did a little more research and based on dimension and shape, it looks like the G37 Gen3's are round tapered RU-4990.

I apologize. The G37 uses the RU-4990. I've gotten so used to doing the 370Z ones. The AEM are a 21203DK. *Fixed in original post.

I replaced with AEM Dry-Flows: AEM 21-203D-XK

I posted a thread about it a while ago. Search for "aem dry flow" so the pics are missing, but they've been on my car since then.

Does anyone know if the replacement filters damage the intakes. I’m trying to decide if I should by the filters straight from Stillen or buy the RU-4990 from Knn

Why would they damage anything?

I was just curious. I just ordered replacement filters from Stillen directly. They charged me 140

You make no.sense. why would a filter damage the intakes?

Actually its a really good question....

I have the gen 3 intakes which come to the front of the grille. If you have ****ty cheap filters which are not designed specifically for that intake it could potentially suck up water during heavy rain.

It's safer to buy straight from Stillen don't cheap out and then end up ****ing up the entire engine.

No it does not make Sense. Cheap filters may damage the engine highly unlikely but filters wont damage the intake pipes. Theyre aluminum lol. Dumb thread

mikluhin97

Did I say they will damage the pipes???
I'm saying cheap filters COULD POTENTIALLY **** up the engine. If they are not properly manufactured they can suck up water since the intake is right behind the grille.
of corse it wont damage the pipes...
