Description

WCFab 4" Intake Kit with Air Box for 2004.5-2005 LLY 6.6L Duramax equipped Chevrolet Silverado or GMC Sierra 2500 / 3500 HD truck.

This high flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts on your diesel for improved engine performance. All new design significantly increases air flow to your turbo producing improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the inner fender. All aluminum construction features large diameter 4" piping with smooth aerodynamic bends to improve intake air velocity, volume, and provide more aggressive engine and turbo sound during acceleration. High quality hardware, silicone boot, seals, and stainless steel t-bolt clamps ensure optimum durability and ease of installation.

Removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with included hydrophobic pre-filter cover, to help keep your MAF sensor, turbo, and engine airways contaminant free.

Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck.

Cool crossbody
Color: Luggage
Lovely little Michael Kors crossbody purse. It is small, so really only holds the essentials, phone, keys, lip balm. It has a nice quality feel to it and I like that the strap is adjustable. The logo looks nice, but it isn't so large that it feels conspicuous, which I also like. Comes packaged very nicely and securely.

Nice size, good quality
Color: Brown/Acorn, Color: Brown/Acorn
Nice small crossbody with an adjustable strap. I am 5'6" and the strap length positions the purse at a comfortable length. It is an original Michael Kors that comes with store quality tags. It was nicely packaged with foam inserts to protect the finishes. The purse is nice and long- enough to hold a full size wallet. There are card slots inside and a zippered compartment. The outside features the traditional Michael Kors print and the inside is a smooth camel colored finish. The magentic clasp works well and the zipper moves smoothly. I took a photo with it on to help with getting a sense of the size. In the photo, the strap is on a middle hole- it could go longer or shorter. It would make a beautiful gift.
