Best Cold Spark Plugs
Hello everyone. it's been awhile since I've posted. Blew up my F23 engine back during Covid, and then had a daughter which put off fixing it for years. Finally almost ready to start it up, after getting a new block machined with CSS closed deck system, oversized K-series pistons, turbo set up, blah blah blah. Wondering the best spark plug to run? I know I need a colder plug and believe I had NGK's in it before, just unsure on the model number, but it's been over 5 years since I driven this thing, and wondering what everyone's running. Running about 300HP TIA!
