O.S. Engines

Speed Tuned 19XZ-B ABC

Finesse and fuel economy for tight, twisty 1/8 scale tracks!

Replacing a .21* with an O.S. 19XZ-B improves fuel economy by 10%. That means 10% more time to rack up laps before you need to pit…and fewer pits overall. And every second you're not in the pits is another second you can add straight to your lead. The O.S. 19XZ-B is the engine that offers you all the fuel economy you want with the performance you need to win. *Compared to an O.S. 21XZ-B with 21J2 carb and 6 mm restrictor.

Displacement: 0.19 cu in (3.1 cc) Output: 2.4 hp @ 34,000 rpm RPM Range: 4,000-40,000 Weight: 12.9 oz (343 g)
