I’ve been using alot of Boostane, probably too much. I’ve been having some issues with timing so I pulled a spark plug out. They are Denso plugs gapped at .22. They look very orange. Not sure if they should all be replaced? Any ideas?
I've had them for 2 years and ~16k miles without issue. Most of my driving is pretty relaxed, but I'm nearly always on Map 5 / E30 and have had nothing but clean logs.
I had a mechanic say that the plugs in the picture weren't able to be put into the stinger because it doesn't have washers on it like the densos I already have in the car. Can anyone comment on if these spark plugs are an ok fit for a tuned stinger? Or should I have just reordered from BMS instead of Amazon?
That's the wrong plug, at least for the 3.3 v6. Spark plugs have two basic styles - a washer seal or a taper seal. You can't swap that. The picture shows a taper seal.
The Denso series for the v6 is IKH - 5345 for stock heat, 5346 for 1 step colder.
