Looking for ways to improve your engine's power and performance? Look no further than upgrading your air filter and intake system with high-flow aftermarket parts from our vast selection. Factory air filters and intake systems are designed for low noise and cost, not maximum performance. Don't settle for restrictive air boxes and intake tubes and cheap paper air filters any longer!

One simple and affordable way to get started is by replacing your paper air filter with an aftermarket performance filter. These filters have several layers of filtration material like cotton gauze, which traps dirt without restricting airflow. And the best part? They can be cleaned and reused, saving you money in the long run.

But for even greater airflow, you'll need to increase the size of your air filter. Our kits attach a larger, high-performance filter to a flexible, universal intake tube or your factory air intake tube, giving you the benefits of a larger filter without breaking the bank. And if you're a hot rodder, you'll love the increased intake noise when you step on the gas.

To really boost your engine's power, replace your restrictive OE air intake tube with an aftermarket intake tube. Our mandrel-bent aluminum or molded polyethylene intake tubes have larger diameters and smoother bends, ensuring better airflow to the throttle body. And for even cooler, denser air, we offer systems that shield the filter from engine heat and locate the air filter outside the engine bay or use a scoop to funnel air to the filter.

For maximum horsepower, upgrade all the way to the cylinder head intake ports with our high-performance MAF sensors, throttle bodies, and intake manifolds. Our MAF sensors are larger in diameter and calibrated to ensure your PCM gets an accurate signal for proper air/fuel ratio control. And we have the right size throttle bodies to increase airflow and horsepower and provide crisp throttle response, no matter your engine's state of tune.

Don't settle for factory air filters and intake systems any longer. Upgrade to high-flow aftermarket parts from our selection and make your engine come alive!
