TD 049 Cylinder and Piston


Dual bypass ports
Sub-induction (SPI)
Dual booster ports (one per side)
(The same porting as TD #4 Cylinders )
Brand new Current Production item

These are special manufacture; whereas we took a #1 Production cylinder, removed the bar in the exhaust ports and lowered the bottom port cut-out to induce SPI. (cannot be used with a muffler)

This cylinder will equal OEM Tee Dee cylinder performance and is currently our highest-performance cylinder.

Inside of exhaust ports will be unplated (not oxided).
