Put perfection in your motorcycle or ATV with Faction MX’s Intake Valves made from 21-4N stainless steel. A material resistant enough to wear evenly for excellent sealing and compression at any RPM. Black nitrite coating and swirl polishing make the valves slide smoothly in their seals and with a set of Faction MX High Rev Springs—which Faction MX recommends—these valves float about as much as a brick. Stick them in your engine when you want consistent, tough valves.

I have been using these for over 90hr and they are still holding strong. Always my first choice for valves. I like the coated valve stem for added life
I have an 04 crf450r which is notorious for eating away valves and after I got the Faction-mx valves i havent had to adjust my valves after nearly 100hrs of riding. would recommend to anyone.
The first box i recived was missing one valve.the valves are boxed in pairs so i sent it back and was sent a new box.The valves in the second box were not the same other then the stem legnth and face diamiter. One was magnetic while the other was not. The two valves were two different weights. The contures of the valve faces were different.
Bought these on a budget figuring I would swap them out for titanium later but they have been working so well they're staying in. They don't seem to bother the high end rev and are very reliable.
These valves are good. can't say they are great because I can't really tell the difference. great money saver and w/ replacement valve springs and seals its great. I have an 05 CRF250R and I can tell that it wants to stay on the gear longer when I let off the gas. pretty good. good investment.
