RJSPHH ls steam Port kit coolant Crossover kit LS Throttle Body Bypass Hose Kit Compatible with GM LS Series Engine LS1 LSX LM7 LR4 LQ4 LS6 L59 LQ9 LM4 L33

Working good so far for 4 months. Don't expect any issues.

Fits my 07 GMC Yukon SLT just fine, same as pictured, worth the price for my vehicle

Its hard to install, directions not great and it leaks a little on the passenger side of the engine.

Fit just like oem

Worked amazing

Don’t fit. Line hits the head bolts. Even in there picture the head bolts aren’t in the head. Very poor quality!

The Machining is sub par for this to fit properly. The fitting on the lines will take a vise, 14mm wrench and some elbow grease to get the fitting sung. After which bolt in. It kinks the line excessively. Do not know if it will leak as others have stated. The supplied teflon tape is almost transparent. Gave two stars as this is a part that controls engine temps and could cause problems if you are not careful. But the quality of the materials are built well. I would not recommend this product.

1 line worked perfectly, the other line however was very disappointing. When warmed to approximately 450 degrees in order to bend it. It snapped. This was very unfortunate due to it being 2AM and halted me in my tracks. Would buy again.
