The problem has been a missfire at cruising speeds.. Link to comment Share on other sites More sharing options...

Im going to run 18psi and about 350rwkw and I thought 1 heat range colder would be needed. Is it not necessary to go to colder plugs on these motors??? Thanks Link to comment Share on other sites More sharing options...

I buy these which are 20 heat range 22 is slightly colder, but when you open the packet the plug inside is AGSP22YE07’s. Used multiple sets but only noticed last time I installed a set. https://www.ebay.com.au/itm/GENUINE-FORD-BA-BF-FALCON-SPARK-PLUG-SET-SK20R7-TO-SUIT-EGAS-LPG-ANTI-BACKFIRE/290628022377?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 Link to comment Share on other sites More sharing options...
Slowxr6t Member 566 Member For: 6y 1m 25d Location: New zealand Posted 27/07/19 01:18 AM Share Posted 27/07/19 01:18 AM I have stock standard plugs in it at moment, iv just been stock piling parts and I'm about to start the big monster garage project soon, Ford over here said they cant get 1 heat range colder, repco said $56 per plug for 1 heat range colder iridium, but that sounds way too much $. No one in nz seems very helpful so far. Link to comment Share on other sites More sharing options...
