Would this fit my hobao mack .21 engine? If not what would Thanks
Asked by Rob Hartrick on 4th November 2016

If your engine uses a normal "non turbo" glow plug, then yes this would fit.

If yours is a turbo head, then we'd reccomend the HPI Turbo plug HPI-1508

I bought a os max 50 engine from a friend , but there was no glow plug. The nearest picture to resemble my engine is a os max fsr , made Japan. They recommended a os number 8. Would this sound about right to you, or what do you think?
Asked by Dougie Mcfern on 25th October 2017

Yes, OS number 8 is a good all round plug - it'd be the first one we'd try!

Asked by Richard Cliff on 4th July 2020
