K&N 33-2440 Air Filter Product Reviews

Sunday, March 11, 2018 - Part 33-2440
Super easy installation on my 2016 Q70 3.7L. Two clips and the tops come off, slide out the retainer tray and gently pull on the old filters to remove them. Ensure the new filters have the longer tab on the topside and reinstall pastic retainer tray, refasten clips and all set to go I haven't seen lower full efficiency, actually just about the same. Overall, better lower end torque and smoother acceleration in the lower RPM range.

Easy install, slight fuel economy reduction of approx 2mpg, but whoa.... did these filters fill in the blanks on power smoother acceleration! Exactly what I expected, and at least another 20hp.
