Spark plugs for R1

[63stick]

Any recommendations for spark plugs for my R1. Some brands seem to perform better than others.

The Champion RJ12-Y’s I installed in my ‘63 R2 seem to go on forever!

The R2 takes different plugs though. I talked with Jon Meyer the other day and I think he said HR5. Unfortunately the piece of paper I wrote it on got brake cleaner on it and no more writing. I hate to call him back up.

Yes you are right… but at this point in time the J12Y’s seem to be a reliable, easily found, universal fit…. (If there actually is such a thing!)

And, I’m my opinion, this plug also works well on ‘non-R’ Studebaker V8’s!

IIRC Champion J12Y plugs were specified by Studebaker for both R1s and R2s.  The modern number might be RJ12YC.

H14Y plugs were spec'd for 259 & 289 engines

J10Y plugs were used on R3s (J10Y are colder than J12Y)

This is IIRC, so someone correct me.

P.S., Autolite 437 & Bosch 7517 have also been recommended previously on the SDC Forum

That sounds right Dwight… but try to find H14Y’s (a Champion plug I always liked) at your local FLAPS quick & in a hurry!!!

I use Autolite Platinum AP85. Champions are now China sourced, and quality is non-existent.
