    Comments about K&N Replacement Air Filter:

    Combine K&N Air Filter and or K&N Intakes with a free flowing exaust or performance exaust and tune-up and you will get a performance gain in power and top end speed.
    I gain HP and top end on my Ford Fusion.
    On my Harley-Davidson's , a 10 MPH top end speed increase with a fresh clean , nicely oiled K&N Air filter. The cleaner you keep the filter the better it is. They make a Spray Can of K&N Filter oil that
    is better and cleaning them is not bad. I keep two filters for example one on the Bike , one in a box or bag in the barn , this way you can change it out quick , keep riding for the day , and then clean the second one at night or in your spare time when you get home , and keep it in stock for a quick change at your next service.

    Comments about K&N Replacement Air Filter:

    I like these filters because my OEM air filters are pricey..this one will pay for it self in a year or so. If you're looking for some kind of big milage gain, this isn't gonna get it..but I think my car runs stronger and I will never buy another air filter again for this car.

    Comments about K&N Replacement Air Filter:

    K&N has re-enforced the filter fiber with expanded metal for added strength. A step up from the usual cheaper / low grade alternatives. A regularly maintained filter will rescue your O2 sensors many miles later. Nothing but the best for my Ford Fusion.

    Comments about K&N Replacement Air Filter:

    This product made more of a difference on my Mercury Milan than it did on the Chevy Venture. Throttle response seems slightly improved and at wide open throttle it feels like it pulls stronger and sounds great...the 3.0 liter engine has a lot of grunt anyway, but this brought a little more life out of it.
