The K&N AirCharger 63-9034 air intake system replaces your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The 63-9034 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. This allows cooler, denser air to be directed through a custom molded intake tube into the engine's throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install requiring only a screwdriver, pliers, socket set, and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Little bit on the small side
Size: XX-Large, Color: Black, Pocket Description: Plain Front
Run a little small, but the quality of the shirt seems to be pretty good. It is thick and nice. Warm and softness are both good.

Impressed for the most part
Size: X-Large, Color: White, Pocket Description: Plain Front
Going to give it 5-stars for now, well see how well they hold up after a few washes.
They for sure feel like nice heavy-weight shirts.
I like them alot for that reason.
They have a boxy-fit though, so not "fitted" at all but thats fine for me because I am using them as under-shirts.

Runs small
Size: XX-Large, Color: Navy
Definitely go a size up. These run a whole size smaller than designated. Material is also heavier than a regular t-shirt. Quality seems okay
