Great examples. Marketing hype versus dyno proven.

Thanks Dave, as you answered my question about the air filter on my new LowRiderST. I have enjoyed the 130 you built for my 20 RoadGlide, what a MONSTER it becomes with a twist of the throttle and a stock riding bike at low speeds thanks to YOUR TUNING.

I keep watching hoping one day to see my roadking on one of the videos

Great information Dave, Keep up the great videos

Well done .👏👏👏

Everyone listen to the mad professor Dave!!! If you want your bike to be the best it can be.

Getting the se extreme wedge put on mine.

Thanks Dave 👍

Very interesting Dave. Thanks

Have the extreme and am very satisfied

Very informative vid. Thank you JD.

Great video. This is why I took my trike to Dave for my work.

That 90 degree filter is for looks only.

Hey Dave, I always watch your videos, love them, always trying to learn, I have a 2020 Road glide Special w/zippers 468, s/e pump& plate, fullsac head pipe, MK 45 mufflers and S&S full size tear drop A/C, how does that filter stack-up Thanks again

Now that is a very informative video. It is difficult for guys like me to know the difference between a true performance add on and just another load of marketing horsecrap. I went with the DK Customs 585 air filter because their dyno tests showed it to be an improvement over stock and a few other brands. How do you really know?? Thanks a ton Dave.

I just started running the no loss Headhoggers a/c it sucks in the air for sure

👍

Sorry could not make out what type air filter you used.

Hey mate ive got that screaming Eagle extreme air cleaner and im looking at changing hopefully up to the new Feuling Ba air filter what’s your thoughts on that Feuling say they’ve done a lot of R&D on it and is a great performance filter

Is this the Extreme Air Cleaner - Circle or Extreme Wedge? Here are multiple extremes

So how do I select an air filter?

i have videos on my 121 stock air filter sucks compared to the wedge

Dave, do you like the S&S stealth air cleaner? I'm considering this after getting my 117 dyno'd the other day with poor numbers.. it has the stock heavy breather on it.

Not sure what the point is here. That is a stock HD filter is fitted to some stock bikes and has to meet emissions regulations. The other obviously does not. Emissions compliance is obtained through cam, mapping, exhaust and intake restrictions. That bike has been cammed, exhaust altered and re-mapped so leaving the stock filter on there is obviously going to restrict the work done. We all know the intake needs opening up.
