Those Dyno Guys - 02 Blocks

The finest sampling blocks on the market! Very few shops on this planet complete more dyno tunes per year than Those Dyno Guys. We took a proven product and improved it in several ways. They have a much larger lateral bite on the pipe for stability. No more rattling loose mid tune.

They are jetted for precise metering to help negate the negative effects of reversion across the 02 sensors.

Finally, they are helicoiled so they don’t strip out after repeated use. Sold in Sets of two. Each set Includes: Qty 2 -02 Blocks, Qty 2 M6×1.0 hold down screws with Copper seals, Siphon tubing.
