Anyone dropped in a K&N 33-5049 in their 2.0 turbo filter box?
Some Malibu owners seem impressed with them.

I did and I like it so far. No performance difference that I can feel, but it lasts forever. I replaced mine after 50k miles since I did not want to clean and oil it. It has a huge surface area compared to our stock filter that is surrounded by plastic.

I picked one up when Amazon had a sale on them, so it was barely more than an OEM filter. But I haven't noticed any changes to sound, MPG or performance. It might be slightly noisier when you really get on it, but that might be me hunting for a difference. If I were paying normal price I wouldn't bother since they have been proven to let more stuff pass, especially for you LJ because I thought you were in the Vegas area. I would want as much filtering of that sandy dust as possible, for me in NNJ it isn't very dusty so it is a calculated risk.

Paper filter has a standard 45K mile interval for changing. That means most people will change it once or maybe twice during typical ownership. Hard pass for me on K&N.

For the 3.6L engine, neither K&N nor the OEM engine filter is currently available in Canada as far as I could work out, from online sellers like Amazon, Canadiantire or knfilters.ca themselves..

Rock Auto ships to Canada. AC Delco Store on Amazon has them as well, but I don't know about shipping to Canada.

Appears 3.6 uses same K&N air filter as TourX, amazon does not ship to Canada?

3.6 Regal uses a different filter number than 2.0 Regal. 3.6 A3209C 2.0 A3210C (AC Delco numbers)

Thought I'd chip in and say I've had the drop in filter then ended up installing the k&n warm air intake (yeah it's not a CAI) and I love it. Awesome induction noise but be prepared cause' people will think you also installed a BOV too 😂also installed an oil catch can coming off the PCV line that normally connects to the air intake.

For the 3.6 it's the 33-5049 effectively

It's interesting that the replacement paper filter folks and the OEM show 2 different filter numbers between the engines where K&N uses just 1. I've never seen the filters side by side to know what the differences might be.

Maybe more filter less plastic on ac delco for one or other?
