Universal 7" Tall Air Filter - High Efficiency Replacement for HVAC, Furnace & AC Units - Perfect for Home, Office & Commercial Use

Threw it on my truck, a 6.6 duramax, the old filter was real bad. I was expecting slight gains in mpg and power because I mean, it was bad before. Cleaned off my maf and map sensors threw the filter on and didn't pick up any gains my mpg actually went down. Average off multiple tanks, driving like I was 70 . It does seem durable and like a quality filter, perhaps it was too small of a filter. May be me needing a larger filter.Its a filter, not sure what else to say. Quality seems just fine. I use this on the inlet side of a inline axial exhaust fan in my garage.I am a 50 yr old car guy. My car is an 09 Charger hemi R/T with R/T. This filter fit my $$K&N$$ cold air intake better than the one from K&N. I will definitely be buying again. A++Great quality filter. Shipped with plenty of packing to not be crushed. Was only replacement for my KN intake filter in 02 Tahoe for a reasonable price.Seems to be a quality productGood product. My 6.0 loves the extra airJust recieved my filter today. I gotta admit that this filter is of better quality then I expected. Fit perfect!I'm using this filter as a back up while cleaning my other ones. I appears to be a very well built filter and the price was great.
