These filters are fantastic. I have them on my current vehicles and used them on my 5 previous ones. They have consistenly added at least 2 miles per gallon to my average fuel consumption. It is easy to see at the cost of fuel how quickly they pay for themselves. Also, they basically have a 100,000 mile guarantee so, you probably won’t have to replace them. I haven’t nor have I had to reoil one. It is much cheaper to burn air than gas. The price from this site was the best I found anywhere.

They sent the right one first time. Have not checked my mileage yet, I am keeping my fingers crossed.

I love these things. They last forever, give more air to the engine (ie better mileage or more power) AND clean the air better as well. Plus, they pay for themselves after about the third time you clean/reuse them vice buying paper filters (which means the rest of the car’s life is gravy).
You need to buy a recharge kit as well which costs ~$10 and is good for 20-ish cleanings. It doesn’t have to be right away as the filter comes ready to go for the first use cycle.
I clean mine about every 25,000 miles or if I notice a drop in gas mileage.
I put them in all the vehicles I maintain; this is my ~7th one in 15 years. I will automatically put one of these in every car I buy. I wish my furnace had a filter this good!
The only vehicle I ever had an issue with was a 2000 Subaru Forester S 2.5 Automatic, it did not seem to perform better with the filter and it needed cleaning constantly.
Dont forget to put the included decal on the filter housing so the filter does not get thrown away during a dealer sevice package (although if a mechanic threw one of these away instead of giving it back to you when you retrieved your car, it would be prima-facie proof that they were incompetent and you should stop going there.)

I am very pleased with the product so far. i haven’t had it long enough to really see a difference in the mileage. But I am preparing to take the Suburban on a trip and check it out.
Also: The item was shipped days before it was scheduled. Great service!
