ACDelco GM A3087C Air Filter: Genuine Original Equipment for Optimal Performance Review

Unlike the last filter I used, this one comes as a filter ring and adapter. Initially I was confused by the installation as the filter border looked the same size as the previous one. After measuring, I realized why it didn't fit. Then I installed the adapter ring and filter inside. It all made sense and worked great!

Installed and the first time the car was used the Check Engine light came on. There were 2 errors related to low air consumption. Cleared the codes and same thing happened with the engine codes when the car was running. I installed an old filter that had many miles on it and the problem went away. No visible problems with the filter. Went back and ordered a replacement brand from WIX.

OEM for my 2010 Silverado Duramax. Seems to be working fine. I've always wondered why GM went with a two-piece filter. Another place to log out, but so far I haven't had any problems. I always worry about changing the air filters on vehicles and equipment. If you don't get it absolutely right, you're likely to ruin your engine. The two-piece construction is another place to screw up.

This air cleaner element has very tight limits. He disabled the MAF sensor code and went into emergency mode. The power dropped immediately and the intake manifold suction gauge immediately turned red. I also have problems with oil in the intake which I think is being sucked through the PVC. It must be fake or defective, do not buy because by the time you find out what it is after claiming the turbine and sensors, the return window has already expired.

Had the same problem as in the review I read, the truck immediately went into emergency mode! OBD11 showed PO1O1 mass or volume flow circuit range/power. Later bought a new Autozone MAF sensor for $100, same problem! Put the old dirty air filter back in the truck, clear the codes (AGAIN) BINGO fixed the PROBLEM! I don't know if that really is an AC DELCO air filter, but it was glued in place. NO AIRFLOW! Autozone for parts now available. 1 star because there are no 0 stars.

Had a standard air filter, not too dirty and no worries. I've made a lot of air filters in my time... Anyway, the 6.6 LMM obviously likes to cause problems rather than tell you what the problem is. Memories of my ex... still, it's most likely your air filter. Big technical error, but try a new filter. "The air filter is a bit dirty, it would be a shame if I didn't give you error codes and put you in emergency mode when you enter a busy street."

2008 Silverado 2500 6.6 Duramax Still got the 'Reduced engine power' message from the Donaldson filter I installed. All sensors checked and for boost leaks, none found. I ended up buying this filter and installing it. 3 months later still no reports of engine or reduced performance. Apparently even the new Donaldson filter will cause this. Use this AC Delco if you're in the same boat. It comes with a ring and filter for installation. Takes less than 5 minutes.

Helps to fix Code P0101 on Gmc Sierra 2500 Duramax 2008. After trying to fix the P0101 code by replacing the MAF sensor, accelerator pedal assembly, cleaning the EGR valve and of unsuccessfully checking for inlet leaks. I figured I'd try replacing a stock K&N replacement filter (worth 250,000 miles) (which always ran dry with no oil or pre-filter) with this factory replacement filter and it immediately cleared the p0101 code I was getting . I've driven almost 2500 miles since transitioning to…

Defective in original packaging. Bought as a warehouse deal but there was no deal at all. I was going on a big trip the next day so I had to rush to my local auto shop when this diesel put the diesel in limp mode right after installation due to severe airflow restriction. I changed the filter at a local shop, everything works. Since I threw away the packaging, I did not return this warehouse deal and simply sent the filter in the bin. I recommend NOT buying it at a discount from Revain stock…
