A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine, and provides a guaranteed increase in horsepower and torque. These systems are paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 90 minutes.

Good quality
Color: Crisp White, Size: Medium
Fit is great, feels like a durable material. Generally a very nice shirt! Bought this for a 5’ 10” male who is 150lbs. Medium was just right, with a little bit of breathing room.

Good for an emergency only
Color: Crisp White, Size: X-Large
Shirts are good overall, but the material is too light ... if you are hairy or have dark skin, you need an undershirt; otherwise, it looks like the shirt is dirty.

Size

love the shirt and they fit well for an overweight man. All the ones I got are consistent in size and you don't see that often.

Excellent style and quality for price
Color: Grey Blue, Size: Medium
Very nice quality and affordable price. Fabric is soft and smooth, very few wrinkles after washing and drying and easy to iron. Seems durable for machine washing and drying. Fits true to size.
