What will a performance air filter do

Air is a critical factor in the internal combustion process that occurs inside of the engine, and ensuring your vehicle has adequate air flow can maximize engine output and efficiency. Fuel economy is improved because high-performance air fiters pull air from outside of the engine bay where the air is cooler. High-performance air filters vary in price greatly depending on your vehicle, the type of performance air filter, and the brand. Performance air filters claim to increase horsepower and improve acceleration, but do they actually work?

To measure differences in horsepower and torque, each filter was put on a Mustang dynamometer, with multiple runs. A VBOX was used to measure real world acceleration differences.

It could also mean the engine pulls in more air, and with more air, the engine can inject more fuel to make more power. They're good filters overall. I live in a rural area so when pollen season hits it can look like a dust storm.

As for power, using the non-scientific "seat of the pants" test method, it does seem there's a wee bit more "punch", but there could also be a secondary factor.

The engine sounds a bit more powerful, so you think it is. That's nice. For those of us who've built up engines for performance, we know power is expensive. It's an easy mod for a stock engine and anyone can do it. Keep the expectations real. What I'd like to see is a comparison between a stock airbox intake and a "cold air" kit. This seems to be all the rage. I have installed a performance one on my SEAT Ibiza FR mainly due to the original stock filter caused a lag on the turbo engine is a 1.

Another thing that is good with the performance filters is that you can wash them remembering to re oil outside once dry and re-use them over and over again rather than buy a new filter each time. Should have had a dirty performance filter too. While the dirty and new OEM filters were nearly identical in their sprints 9. The CarQuest filter registered a mph sprint of 8. Yes, the aftermarket performance air filters do work. But, don't expect oodles of extra ponies to suddenly show up when mashing the throttle.
