Markku Posted April 30, 2023 Report Posted April 30, 2023 I have 8 Tempest URHM38E plugs I pulled from my IO360 A3B6D with 50 hours on them since new. 3/4"-20 threads massive electrode. Cleaned, gapped and resistance tested. Excellent condition. $160 plus shipping. I replaced the engine with A3B6 which came with 5/8"-24 plugs.
