From the PE turbo installation guide
"The calorific value of the engine increases by use of this MR-S Turbo Kit. You need to raise the heat value of the ignition plug"
Any suggestions for some hotter plugs?
How hotter do you think you need to go,
If it low boost?

I am not getting this.
Arent you supposed to go a grade cooler for a turbo install?
TTE turbo has a reccomended plug one grade cooler than stock.
If I recall some manufacturers go higher number some lower number so that's probably where the confusions come from, you'd expect better wording from someone providing a kit though. unless that's not it.

Same thing really. You go a grade cooler is in fact picking a hotter rated plug if that makes any sense.
A cooler plug has a higher number, if ngk
Cooler = moves heat from tip to engine quicker
I Ran 2 stage cooler plugs (8) in a 100hp hotter (as spinning much quicker supercharged) mini engine
I'm assuming a low boost turbo runs cooler than the mini
Far better to be too cool and foul, rather than to be too hot and suffer pre det
All as above.
Stock = plug rating of 5
TTE = plug rating of 6
So higher number - cooler plug - as per Scott and R Buck
