Thanks to construction, K&N oil filters have gained recognition of the most demanding drivers and are one of the few used in competitive motorsport. These filters are distinguished by a filtration layer that does not limit oil flow.
The advantages of filters are:
- Strengthened construction of external walls reducing the risk of mechanical damage
- Head for easy filter operation using standard flat keys
- Hole in the head, enabling the cotter pin to be required in many motor sport disciplines.
An additional advantage is the internal valve closing the flow after a pressure drop, which protects the engine against dry starting.
The K&N sports oil filters are an ideal solution for all users of cars that care about the efficiency and safety of their engine and are looking for the highest quality products.

Super soft, looks and feels lovely
Color: Cream (Double-sided Faux Fur Bubble), Size: Throw (50" x 60")
LThis is a double sided faux fur blanket (with sides have the same slightly bubbled fur. It iz slightly bubbled looking, not as bubbly as the picture makes it seem. The two sides are sealed around the edge, but not sewn or tied in anyway throughout the blanket, so the two sides are free to move on theinside of the. Blanket. It is extremely soft, and my dog, who is old and going blind actively seeks out this particular blanket to make his nest in. He loves it, and so do I. I got it discounted in white, a d know at some point it won't look white any.ore. I'll try to die it after it gets a little grungy looking. Till then, it looks and feels luxurious. I only wish it were joined together in the middle, and more "bubbly" looking. It's a bit heavy by itself for summer nights, but feels warm down cozy in colder times. I got the throw size, it seems a bit smaller than I expected it to be.

Warm and cuddly!
Color: Cream (Double-sided Faux Fur Bubble), Size: Throw (50" x 60")
I love this double sided blanket!! It is sooo soft and warm. I got the creme color. I don’t understand the reviewers that say that it is hard to fold or that it slips against itself. Mine has two edges/seams that are sewn well and it’s simple to fold after use. I just look for the tag which is on one seam and fold from there. Great buy too!!

Super soft, cozy, and a beautiful addition to the bed
Color: Khaki, Size: Queen(90×90in)
This blanket is absolutely beautiful and feels just as good as it looks.
It’s incredibly soft to the touch and has that warm, cozy feel that makes you want to curl up right away. The texture adds a nice touch without being too heavy, and it lays really nicely on the bed.
My daughter immediately claimed it for her room and has been loving it ever since—it’s quickly become her go-to blanket.
It also seems very well made and holds its shape nicely after use. Overall, a great mix of comfort and style.

COZY!!! WARM, lightweight king size throw.
Beautiful color of sage green, my favorite, color is the perfect shade!! King size is 108x90 it is huge, soft, plush, cuddle up watch tv, read a book with hot chocolate Fall Time!!
Totally Happy with this purchase! It can be used anywhere or anytime, get a king and there is lots of room to share.
The blanket has a diamond floral pattern on one side, the other is a plain soft, plush fabric.
Machine wash on cold. I am told by my Daughter who has one, it washes well and is a very durable blanket. Always great to have a real known person give you great feedback before you buy.
Great value and purchase!!
Happy Fall and Cuddling up in a nice blanket!
