Built specifically for K-Series cars competing in the SFWD / AWD classes, this 1400HP+ rated air-to-air intercooler combines our MASSIVE 6" thick, 1-piece core with trick smooth-flowing endtanks to ensure optimum flow over the entire intercooler core surface.

Our unique intercooler design allows you to achieve maximum cooling effectiveness with a smaller package than traditional air-to-air intercoolers, opening up valuable space in both front corners of the vehicle for other components that would otherwise be occupied by intercooler piping. The offset-height endtanks make this intercooler perfect for K-Series centerfeed or side outlet intake manifold setups. The endtanks are carefully hand-formed from H-3 5052 aluminum and fully TIG welded in house.

This intercooler core is efficiently cooling intake air temperatures for many cars currently in competition, generating very high boost levels in excess of 60+ psi.

Our K-Series SFWD / AWD intercooler comes standard with bead rolled 3" inlet & 3.5" outlets, which we have made short in length to accommodate a tighter clearance piping setup.

All units ship complete with the SpeedFactory logo stenciled on the face of the core and come with M8x1.25mm aluminum mounting bungs already attached for easy installation.

Vibrant Performance Vanjen clamps are also available upon request for faster, more secure charge pipe connections. Please call or email us before you place your order if you would like the Vanjen flanges welded to your intercooler.

Comfortable
Material Type: Black - 2 Pairs, Size: X-Large, Material Type: Black - 2 Pairs, Size: X-Large
I have very sensitive skin, so I usually need to wear socks at all times. These are especially comfortable because they don’t cover the toes, which helps with temperature control. The material is well-balanced—not too thick or too thin—and has just the right amount of stretch. I also appreciate the large traction area, which adds stability. Another plus is that they are completely fragrance-free.

Great Heel Socks
Material Type: Black - 3 Pairs, Size: Large
I don't know how they work but it's wonderful. I've had rough heel problems for a long time. I wear these everyday and my heels are not rough. They're not baby bottom smooth, but they are not ever going to be. These heel socks also oncce they are properly positioned snap onto the heel. Properly positioning them is easy when you put them on your foot with the heel cup in the correct orientation.

Too small
Material Type: Gray - 3 Pairs, Size: X-Large
Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.

Good fit
Material Type: Black - 3 Pairs, Size: X-Large
My husband just started using these and they feel comfortable. Hasn't used them long enough to see if his heels are better. He has a high arch so I bought him the XL and they fit perfectly.

No more painful cracked heels! These really do work!
Material Type: Black - 3 Pairs, Size: X-Large
These really do work well. This is one of the first winters that I have not experienced painful, cracked heels. They are long lasting, and definitely make my heels smoother and softer after wearing them. For the first few times wearing them I simply went with the moisturizer embedded in them. After a few uses I then covered my heels with Aquaphor Advanced Therapy Healing Ointment. This worked even better, and I would recommend it. I am very glad I bought these. Of note, I have really big feet that are quite wide and the XL are a little snug but not uncomfortably so. I use them overnight, but also have worn them under socks and they work fine.
