Hello, I am planning to replace the stock spark plugs of my 308 GTB single distributor electronic ignition with iridium spark plugs. My local parts store has stock of Denso IW 22 and IW24 irridum spark plugs could any of these replace the stock spark plugs
Waste of money. Ngk b85es iirc are less than 2$ each and in stock locally. Set of those, pertronix and an Italian tune up are all you need. Happy driving.
There are also these from NGK if you do want to go iridium, I put in a 1980 308 GTB as a reference. Most every spark plug manufacturer has a search function on their site for a specific car and you can get plugs online in a day or 2. Don't just get whats in stock locally, get a true upgrade. https://www.ngk.com/Automotive-NGK-c1411.aspx
