Fleece Performance 03-07 Dodge 5.9L Cummins Coolant Bypass Kit (03-05 Auto Trans)Another product from Fleece Performance built out of necessity is the 2003 2013 Cummins Coolant Bypass kit. The Cummins engine cooling system was designed to adequately cool a 300 350hp engine. When the horsepower is increased there is an increased demand on the cooling system. The rear cylinders suffer from a lack of coolant flow, and therefore, experience the highest coolant temperatures. This can cause excessive pressure to build in the system,

Soft & fluffy. Stuffy arm rest.
Color: Purple, Color: Purple
Soft and fluffy & my fav color purps. Now I'm looking for other purple accessories to go with my 2021 Honda CRV. I don't think this cover would be be enough for a large SUV arm rest such as a Navigator... But yea, order if you want some color & funk in the ride

Return refund impossible to receive also it’s tacky looking
Color: Black
First off this item said it was fit, but it did not second of all I went to return it and they could only be returned to the original payment method my credit card. My bank is not showing anything. Amazon is zero help trying to say it went back on a gift balance, which I have photo proof that both are incorrect. I tried to reach out to the seller and they were also zero help so I advise one not to buy this because it’s small and cheap looking too you can’t get your refund back.

It’s so so but ok
Color: Champagne
The color is good and the hair is not as silky as my car seat or seatbelt covers. Also the hairs really get matted. It may just be from elbows but it gets so matted it is hard to undo. And when you do get it good it happens right again and frankly looks bad and unkempt. Other than that it fits right and is more comfy than original so I leave it on. Even with vacuum at car wash the mats stay so it seems eventually it will be too much. I have had it about a month. Maybe a shorter pile is a better option for armrest, like shearling pile. I’ll try that when this one is too far gone. It wasn’t expensive and is still worth the money to not have a blazing hot armrest so I m good for now.

The color is beautiful. Is soft, but it runs very short doesn’t fit my car. I’ve had it for six months and now it looks like a dirty dog lol
