If YouTube channels got awards, I would nominate yours for “Most Useful Channel”. 💯

We've legitimately used this man's videos to change what kind of tools and parts etc that we use on the generators we build at my work, his videos have actually solved some issues we've been dealing with and helped make our products better. Can't give any better praise than that

I really appreciate that I can come back and watch years later as a reference. Blessings

I just wanted to come back and say thanks for taking the time to do this. There are so many misinformed people and I was one of them before this. I share this video at least once every three months when discussions about air filters and cold air intakes comes up.

If products had a stamp saying “project farm tested” I’m buying

As others have mentioned, would love to see something similar done with cabin air filters. Keep up the great work!

As a mechanic/ owner operator of a small shop, and a youtuber myself, I love this channel, always very through and well planned out! Stay awesome 😊

I now consider YOUR tests more authoritative than ad's, testimonials, or endorsements. Thanks!

I’ve used OEM or Wix for years in a variety of vehicles, so I am very glad the Wix did well. Really appreciate the passion and thoroughness you put into your videos. Looking forward to what’s next, take care!

So glad I watched this. Used to swear by K&N, had no idea the potential damage it was causing.

Particle counter! Dude!! When I first started watching you ..you were like: Lets see how long this lawn mower engine runs on human pee! You are now outdoing Consumer Reports! God, I hope you are getting paid for this. Obviously...awesome job as usual!

After all his hard work, he still makes time to respond to every comment. Best YouTuber ever! Thank you sir!!
@joshuamoore1091 4 years ago

This guy has a gift. And he doesn't bother us with too much talking. He just gets to the point and tells you what you need to know. I've come to this channel a few times and I haven't wasted anytime with his videos. Very nice and informative. I am grateful!

Thank you. I have been saying it for decades that K&N is great for flow but terrible on filtration. I have seen many diesels with K&Ns come in with dusted turbo wheels (saw blading) with no obvious pre turbo air leaks. I avoid them on all my vehicles.
