Noticeable decrease in time from ignition to idle rpms, engine runs quieter too. Good deal.

I have a model year 2000 Ford Explorer Limited Edition V - 6 4.0 Liter fuel injection SOHC engine. Now even though my vehicle is 18 years old I've noticed that it has more giddy up and go power ever since I installed the K & N air filter. At first the air filter might seem a bit pricey but in the long term it should save me around $40.00 a year in terms of maintenance and best of all it is environmentally friendly.

Fast shipping, the air filter is wonderful. I test the filter right away, better idle no motor shaking anymore. For the power, you feel it above 4500 rpm, the motor is more powerful and you realy feel it. I use the gold K&N oil filter too. Its the best filter out there. Nothing else will go in my car.

I installed the new filter a couple of weeks ago. My 2001 Ford Ranger seems to have more pep. The increase is noticeable, especially when accellerating at highway speeds. I am pleased.
