The K&N 33-2135 panel filter was found compatible with the stock GM air box, although the filter depth was approximately 0.25″ shorter than the AC-Delco OEM paper filter it replaced – See photo below. Performance increases were evident immediately, as was a far smoother idle upon cold startup. The OEM filter was in service for approximately 12 months and 10k miles, and it was not excessively soiled and certainly not occluded (plugged). However, the typical rough idle experienced on cold starts for approximately 5 seconds was completely eliminated solely by replacing the OEM paper filter with this K&N panel filter. Clearly the MAF sensor was affected by the new airflow dynamic, and apparently this resulted in a leaner cold start Air-Fuel mixture. Fuel economy (aka mileage) was unchanged as monitored after two tankfulls of fuel, but engine slew rate (aka acceleration) was noticeably increased in magnitude (i.e. the vehicle was found to accelerate faster). Additionally, the linearity of the acceleration curve relative to the respective command by the pedal position was greatly improved after changing to the K&N air filter. The goal was to improve cold start idle roughness and improve fuel economy, and this solution solved one of the two obvious design limitations present in the 2010 6.2l Cadillac L94 engine. Overall, this solution was viable, but the K&N air filter is still quite expensive as compared to disposable paper filters.

I think everyone should change their filter in their car or truck to a k&N filter. It makes your vehicle run better and saves you money.

I replaced the air filter on my 2003 Cadillac Escalade 6.0 with this K&N one. I have a stock set up with only a Flowmaster muffler as an upgrade. It was a perfect fit with no modifications needed to install. The sound under acceleration has a bit more base which is good. I have had it on for a few weeks and I can’t say I have seen a noticeable performance increase through acceleration or general power. After install as some have reported, I did not have any issues with weird idle or a CEL. It does make the muffler sounds better and my MPG are steady at about 13. I think I will need to give it a few months to see if there are any longer term changes. I am happy with the purchase.

This is the eighth vehicle for which I have purchased this filter. The product is outstanding and performs as they stay in their advertisement.
I usually get 8 to 10% improvement in fuel economy by using this filter.
The most important thing to remember when cleaning and re-oiling is to use as minimal oil as possible on the filter. Also, these are made in the USA.

I’ve always been happy with K&N filters. This fits perfectly and my truck breathes a lot easier. I have noticed a small increase in gas mileage as well.

Have used these filters for years on my 07 dodge it now has over 300,000 on it. Have purchased a filter for both my 85 Ford and 15 gmc.
