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 hood Ram Air duct and inner fender.

Very nice. Runs small
Color: A-white Flowers Bf290, Size: 3X-Large
You’re beautiful shirt! The fabric is soft and very comfortable to wear. My only concern is that I find it runs small to size. I ordered one and then I ordered one a larger size and that fits better. I received many compliments on this shirt. I recommend this shirt for its comfort.

Very nice style and material
Color: Maple Leaf Wf157, Size: X-Large, Color: Maple Leaf Wf157, Size: X-Large
This top fit perfectly. I liked the v-neck. The material was so nice -- a tiny bit silky and not clingy. I loved the colors too. But I returned it, because for me (and I know this is really picky), the leaves and flowers were too big for my liking. I felt old in it.
