What do you guys think about Bosch PlatinumIR Fusion Spark Plug

 

Anyone

 

stay away from anything that is platinum, the 4.7 hate them, stick with the copper core

 

i just changed out from ngk iridiums and the electrode was almost gone. i went with the autolite copper core much cheaper

 

Try E3s.....please. No one has reviewed them for the Dak yet. I've had Platinums, Autolites, and Iridiums. The Iridiums were the best in the HO motor....but the difference were small. I've read good things about the E3s, but that could be all marketing.

 

We're all waiting for you to try them.

In all seriousness though unless somebody shows remarkable improvements with something else I've been very happy with the Autolite 3923 plugs and plan to keep using those.

 

I did some digging the E-3 for the HO motor "j" code is an E3.64 and the "n" motor is an E3.48.


The cross reference for an autolite 3923 is the E3.64 however.


I have an " n " motor. I may try some soon. Which do you guys recommend i go with? the 64's or 48's?


I have a magnaflow exhaust, k&n, jet chip (for now) , fastman tb and an electric fan coming.

 

E3.64

 

ordered some e3.64's today, ill report back.
