The CSF B58 Thermal Rejection Competition Spacer is the next level upgrade for the B58 Super Manifold (CSF #8200). Made from KIYLEX, a patented revolutionary high-performance final stage polymer. KIYLEX is as strong as aluminum and can withstand temperatures up to 1100'F. This spacer is designed to insulate the intake manifold from conductive heat transfer from the cylinder head. This thermal barrier reduces manifold temperatures which helps lower Intake Air Temperatures (IATs), improve charge air cooler efficiency, and combats heat soak. CSF is the exclusive distributor for the KIYLEX Intake Manifold Spacer for the B58 Motor.The addition of the Thermal Rejection Spacer is especially useful for Drag/Roll-Racing Events where vehicles typically sit in staging lanes in-between racing. This causes extreme heat soak to the liquid-to-air manifold as there is not sufficient airflow passing over the front mount heat exchanger when the car is idling (which is responsible for cooling the charge air fluid that runs through the manifold). This causes the starting IATs on subsequent runs to be higher than on the initial run.The B58 Super Manifold is made from Billet Aluminum and 100% Tig Welded for strength, which allows it to be able to withstand higher boost pressures compared to the OEM plastic manifold. Aluminum has higher thermal conductivity than plastic resulting in a higher rate of heat transfer between the cylinder head and manifold. Adding the Thermal Rejection Spacer reduces heat transfer between the two metal components (cylinder head & manifold). The spacer absorbs the heat from the cylinder head and dissipates it rather than transferring it to the manifold.The Thermal Rejection Competition Spacer was designed for vehicles competing in motorsports who demand the absolute best cooling in order to gain a competitive edge. With that being said, there are significant advantages to adding this spacer upgrade to any vehicle with the CSF B58 Super Manifold installed.

Good quality and value for my son!
Number of Items: 5, Color: Black/Sport Grey/Charcoal, Size: Large
I bought the Gildan Men’s Crew T-Shirts multipack on Amazon for my 12-year-old son, who is on the heavier side and thus sometimes difficult to shop for. Pre-teen kids grow fast and go through clothes quickly, so I didn’t want to spend a lot of money on basics he’ll probably outgrow in a year. These shirts are really affordable, especially for a multipack, and the quality is surprisingly good for the price. The fabric is soft and comfortable, and my son says they feel good to wear all day at school. They’re lightweight and did not shrink after washing. I also like that the shirts don’t get stretched out like some cheaper T-shirts do. The fit works well for him too. They’re simple, classic crew neck tees that can be worn on their own or layered under hoodies and jackets. We’ve used them for school and just everyday wear. Another thing I appreciate is that they’re easy to care for. I just toss them in the wash and dryer and they come out looking fine every time. Overall, these are a great value. If you need affordable, comfortable basic T-shirts for a growing kid (or an adult!), this pack is definitely worth buying.

Nice

My husband really likes the quality of these t-shirts. They fit nicely and dont have a sagging neckline as some t-shirts tend to have. The colors are nice and they wash up well. Not a heavy so comfortable for everyday use whether relaxing, doing yard work etc

Great t shirts
Number of Items: 5, Color: Navy/Heather Navy/Indigo Blue, Size: Large
Great t shirts. They fit great, and are very comfy as an under shirt or just a solid color shirt. Have washed them multiple times and they still hold up good, don’t wrinkle easy, and colors have stayed nice. The fit is great, can definitely be used for work, gym, whatever, just good comfy shirts
