Ar103 vs xp103 kr

[fbm]

How much more or do you guys think I will have if I go from autolite ar103 to xp103

[fbm]

How much more kr

[Fivefingerdeathpunch]

I don't think the swap will change anything.

I swapped from copper tip 104's to iridium 104's and had several degrees more kr. had more kr when I had the iridium 103's as opposed to the copper 103's as well.

I dont bother with iridium plugs anymore.

[fbm]

How many degrees of kr should I expect

[SgtMarshal]

4-5 more, I think

Ask the engine whisperer.

Thats not a question we can answer, the motor will let you know.

One or two degrees is worth it the change for me but any more than that and I might consider just staying with conventional plugs
