Thanks for all the info.Have you played with your tuning much on sand? We race in the dunes and do not have the benefit of a groomed/consistent surface or timing lights to accurately measure changes. I've played with my base pressure some ( in the dunes) and found the results hard to discern because of the reasons I mentioned. Any thoughts/ theories on that?

Actually they work great in a drag bike. Sent from a van down by the river

There must be inconsistencies in the filter media. For some people they work great..for others , they don't. Do you want filters that have inconsistencies in the manufacturing? If it's inconsistent in one way it very well could be in another. If so , run them. It's obvious you want to pinch pennies here. That's the ONLY reason someone would run them instead of genuine K&N's. There's no other benefit to them. If it was just an isolated experience on my part, I'd say it was something I did or just a fluke. But I had 4 other people confirm that the same thing happened to them. The the shop I talked to confirmed they had 6-7 customers who had issues too. ..so take it as you will. Sent from a van down by the river

Yea. They were boss 4acing. I believe there is another generic brand out there too. They are sold through carting companies mostly.Like I said though.. I'll just stick with the real deal. Why risk a high dollar engine over a couple bucks in air filter. .imo. Sent from a van down by the river

Yea. I know several people who have them and they have zero issues. I also know several people and a performance shop that have had nothing but problems with them. Maybe it's a quality control issue ..Some inconsistencies in the filter media etc? Sent from a van down by the river

I prefer using only name brand TRUE k&n's. The set of knockoffs I had held oil waaay to bad and you couldn't get it all out. Sent from a van down by the river

Told you that their probably A.R. carcasses. Sent from a van down by the river

You're porting it AFTER boring it? I wouldn't recommend that for a new guy. Or maybe you've done several. .i didn't read the thread. Sent from a van down by the river

Calling "dips" before knowing the price...FTMFW! Sent from my SCH-R970 using Tapatalk

If you bought this one all you would need is one of JDS sprocket/rotor guards. Check them out. Sent from my SCH-R970 using Tapatalk

Make reasonable offers. Sent from my SCH-R970 using Tapatalk

No way those SS wheels are lighter than stock wheels. Sent from my SCH-R970 using Tapatalk

You had it right the first time....at least somewhat. Sent from my SCH-R970 using Tapatalk

To the OP. You'd be crazy NOT to buy these. Your getting parts that will be checked out by an unbiased party and from a good seller that only has good stuff! Don't screw around and end up missing them. Sent from my SCH-R970 using Tapatalk
