I bought a REDS 521 Sport engine for my Tekno truggy. I am currently breaking it in and am looking to get a spare glow plug or 2 to have on hand, just in case. I went to my LHS and he didn't have any plugs for a REDS engine but sold me a plug for an OS engine. He said it would work fine but I would have to use OS plugs from then on because it would change the taper of the head from what it is now with the stock plug. Keep in mind these are turbo plugs with the taper sealing bore.
1.) is this correct? Will it change the stock taper in the head if I install the OS plug?
2.) Do different plug manufacturers have different tapers on their plugs?
3.) Should I order some REDS plugs and return these?
I compared the 2 different plugs the best I could w/o removing the OS plug from the packaging and I really couldn't tell much difference, other than the length of the tapered section seemed a little longer on the REDS.
Anyone have any experience with moving back and forth between plug manufacturers?
