This high-flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly replaces your diesel's restrictive plastic factory parts for improved engine performance.

All aluminum construction features large diameter 4" piping with smooth aerodynamic bends to improve intake air velocity and volume and provide more aggressive engine and turbo sound during acceleration.

The removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with an included hydrophobic pre-filter cover to help keep your MAF sensor, turbo, and engine airways contaminant-free. The critical ram air duct seal has been moved to the bottom of the hood for a clean engine compartment appearance.

No bow tie
Color: Burgundy, Size: XX-Large
Perfect fit for my son he's 6'2" about 220lbs. He ordered 2XL . I would've gave it 5 stars but he did not receive the bow tie, and his prom is tomorrow! Now I gotta go out snd spend more money buying the bow tie separately.

Sharp suit
Color: Black, Size: X-Small, Color: Black, Size: X-Small
The quality of the suit is very nice. The material feels thick and does not feel cheap at all. My son and I were both very pleased with this three piece suit altogether. We went off of size recommendation and due to personal preference we both agreed if we weren’t already in time crunch we would’ve sized up one size. Still managed to make it work and looked very sharp.
He is 5’10” 150lbs - size ordered extra small
