K&N 33-2252 High Performance Replacement Air Filter

I replaced a rather overly-thick paper air filter that was pretty jammed up with this one in my 07 Vibe. It made a very noticeable difference in acceleration. In fact, the engine had a bit more of a noticeable rumble at idle and sounded a lot more aggressive. I ran a "what speed can I get to" on the same uphill onramp test twice before and three times after. It was a little over 10MPH faster on average at the top of the ramp at 11F air temp. It has a predictable automatic transmission as well so it was a fair test. The magic question of how much horsepower can you gain in any given car can usually be answered by asking how badly designed is the stock air intake? Apparently in the Vibe, it's awful. So drop one in and get some POWER!

I always looked at the K&N products as I kept buying those replacement air filtration products. Unable to justify the costs of these products built for the same purpose but at such different price points. After spending 2x the amount of your K&N air filter I checked the book for the model No. for the vehicles I'd be buying for. I opened the boxes and examined the deeply red cloth element w/it's soft silicone rubber gasket.This IS an excellent product! My German Grandfather who worked all his life at MACK trucks,earning de-ferments from both world wars his work was so needed. HE would really recognize the Quality+Craftmanship of a co. whose product is made by workers who know its value. My father said Only rich men can afford to buy cheap products and your 1,000,000 quality guaranteed warranty says more than any slogan or t.v. ad could. I bought those filters that day and I put 1 in a 2004 Toyota Corrolla 1.8L, not an image of speed. I had already installed that VORNADO thing on all the vehicles but despite a slight increase in fuel economy not much else. But with the addition of the K&N I felt like I had another 2 cylinders! It breathed much easier, didn't down-shift as often nor easily as it did B4 on over-passes and inclines. It realy sold me on the highway. When passing or just merging it's torque had a more lengthy power-band where it just seemed to have the lungs and determination to just keep on going! I eagerly cleaned & re-oiled it, B4 it needed it but I just love the darn thing! While it was drying, I recommend all to buy the Re-Charger Kit at time of purchase as we all know it's better to have it on hand when needed than to need it and NOT have it on hand! So it's drying and I return the TOYOTA MFG OEM air filter run it around then remove the VORNADO to get the intake area clean. Run it - that w/oem filter, notice even greater dive in performance parameters! When I install the K&N I continue my experiment. Just your filter and it's feeling real eager,I add the Vornado thing again and that combo brings together a increase in driving fun,mpg's and torque & hp though I'm not able to quantify the latter two I sure feel it in the seat of my pants. I tell all that the small improvements like adding your products and investing in 4 high quality tires for 3 seasons and 4 Blizzak Snow tires for winter and other simple enthusiast upgrades can add to the enjoyment and life of its engine working right to most any car/truck Keep up the quality and good work-maybe the research into other new products to us loyal devotee's out here!
