I buy AC Delco filters for our fleet all the time. I pay about 1/3 the amount a GM dealer sells them across the counter for. Same filter, the money goes to the dealers bottom line, as GM sets the price, the dealer shops and buys at the lowest price he can, yet sells them at a price GM determined would give him a reasonable mark up if he bought them directly from GM, as intended. Now, Yamaha isn't GM, and I am unaware of any competition in the marketplace for oem Yami filters. But, unless that cannister contains unobtanium (and I've had them apart and looked, they don't), there's just no way that price can be arrived at except through pure and simple excessive mark up.
The Yamaha oem filter
The Purolator
I use the Pure 1 because it's a better filter, an all around better filter. Better construction, better relief valve construction (at 17 psi I might add, I believe but cannot confirm the Yam is 18 psi), the Yam used paper end caps, ala Fram, generally acknowledged to be a piece of **** by motorheads everywhere, the Pure does not. The Genny Yam filter uses a 25 cent piece of stamped steel as a relief valve, not unlike those found in $1.99 generic junk filters, the Pure 1 a coil spring. Tell me how accurate do you think that stamping is at maintaining 18 psi exactly? Which one, if all other conditions were eliminated, would you rather have on your hi-perf favorite toy? Note the above photo isn't even the Pure 1, built to a yet higher standard, yet still half the price of that Yami junk. Now I buy and believe in oem parts for a lot of reasons, but it isn't a hard and fast rule. One must research what one uses-and make decisions based on facts and not marketing or claims, as has been said. The informed consumer is a dangerous animal, marketing types tremble in fear the world over when people start making informed purchasing decisions.
Edit-the Yam filter is designed to-get this-relieve at 17.19 to 26.01 lbs, near as I can calculate. Now, thats precision.
