working on an old 1zzfe pre vvti with a waste spark design. The old spark plugs are oe copper plugs, and the owner brought me some iridium denso twin tip design plugs. Not the same plug so i didnt want to install these. He pulled out the denso catalog and these are recommended by them, and are a fit according to RA as well.
Do these actually work?
For reference the ones in the engine, denso BKR5EKB-11.
The ones that were going to go in, denso 4701
