Magnum Flow Pro Dry S Panel Gray Air Filter (31-10121) by aFe. Constructed with 100% polyurethane on all sides, this high-flow, oiled OE replacement performance filter will outflow the stock filter for improved horsepower and torque. The PRO DRY S performance air filter uses three layers of progressively finer mesh media to provide maximum airflow for best performance results. Washable and reusable for multiple cleaning cycles, the tall, open, evenly spaced pleats provide excellent dust holding capacity for a longer service cycle between cleanings. An integrated urethane bump seal insures tight, no leak seal over the life of the filter.

This filter features a 3-layer progressive, to provide maximum flow with excellent filtration. The progressive layering of media allows the filter to flow at high levels even when dirty. The Pro DRY S non-oiled synthetic air filter requires no oils for cleaning for maximum convenience. aFe performance air filters use a rounded pleat design which produces more useable filter surface area for increased flow and greater dust holding capacity. This pliable sealing surface conforms to even the most uneven filter housing. This design eliminates the use of gaskets or sealants. The soft urethane construction always goes back to its original form so you will never compress the bump seal. This makes for a perfect filter fit and sealing surface every time. aFe Power performance air filters are constructed using full 360 degree urethane frames. This construction allows for a proper OE style fit with excellent filter strength.

The company was founded in 1999 with an initial concentration on high performance air filters.

I just got it changed about 30 min ago and the engine sounds like a little cat
Size: 5 L
My Audi factory setting says I should use VW 508.00. Somewhere online it says 5w-40. It's 82000 miles and I decided to give it a shot to go 0W-20 which is what VW508.00 is. I just got it changed about 30 min ago and the engine sounds like a little cat. The gas pedal feel is very smooth, there's definitely less resistance when pushing forward. In Sports mode driving, the engine is not as loud and the lag or drag is noticeably less. And when it hits 100k, I will do a engine flush to see if I can get further improvements. So far, I really love Liqui Moly. I used to use it on my S500 and it was very smooth. A little more money goes a long way! Don't settle for less for your German cars. Update: I just did another 1000 miles in a week to Vegas and back. The fuel economy improved about 20%. The power increase is amazing. I could notice when I am going fast, the sustained speed at high speed is easy and continuous, It doesn't just hit a snag when your foot is off the pedal. And the engine is definitely a lot quieter and smoother. I am amazed at the overall improvement after using this oil. No other oil will do from now on.

Do it!
Size: 5 L
Use it in a 14 Sierra. Get about 7500 miles an oil change going off the oil life monitor but I drive rough and the trucks modded. Pricier than others, but I feel it’s worth it. Truck runs smoother than what was in it.
