    Works with ez start and pull starter
  

*by M***  on Reviewed in the United States on February 18, 2023*

Bought these to convert my nitro slash and Revo 2.5r to pull start. Direct fit for both the 3.3 and 2.5 motors. Clean them often and haven't had any issues. Got tired of bad glow plug connections and carrying that starter wand and spare batteries around.

*by T***H on Reviewed in the United States on February 6, 2016*

I was having trouble starting my tmaxx 2.5 so I bought this  just in case. I removed the original and cleaned it out with WD40 and reinstalled it and it has started perfectly since. I actually have more fuel ran through it since cleaning the bearing than I did when it first starting acting up. Before buying I recommend removing the one you have and cleaning it so you don't have a $15-$20 part you will probably never need sitting in your tool box like I do.
