Don't know if this product actually does what it states it will do, but it does "look" better than the stock one, which is why I purchased it. Make sure that you make sure it's snug after you first ride.
The twin air oil filter cap looks great on the bike.
You might have to re use the stock o rings on the 2012 KX450f. The o rings that came with it were a little thinner than stock and let oil seep past.
I purchased this for my 2013 crf450r and as I changed it out I noticed that it does not have the oil ports to force the oil to the oil filter center like the OEM filter cap has. Does this matter? Is the oil still being filtered?
This should have the oil ports machined into the cap, it should look like photos i have attached. If it does not look this way, please give our Customer Service Department a call and we can further assist you.
