FTO AUSTRALIA

Is it advisable to run a colder plug for forced induction even a low boost setup around 8psi?
I used to run Denso IK22's previously and got away with but just wondering if I should run IK24's or is there a better plug entirely?

From memory the FTO, gpx namely uses a 7 heat plug?
If so then that's fine, you won't need anything else.

If they use a 6, then you could go a 7, but I wouldn't go anything lower than 6...

Yeah it depends what you're going to use it for.

If it's a streeter, u don't want colder than 7 otherwise the plug will gum up idling around town.

If it's a racer you could go as cold as a 9. From memory I'm running a 9 in the racecar (non turbo), but only cause I had an almost new set of Iridiums from my previous racecar (turbo Supra) and they've been fine in the FTO, but I rarely run the engine under 4000 revs

Dont forget, you're are talking about NGKs ^^ I.e, the higher the number the colder the plug.

With other manufacturers like Bosch & Champion, it goes the other way (ie the colder the plug, the lower the number)



Oh & FYI, I use the NGK Platinums, PFR6J-11.

Is Champion on drugs or what

And WTF is a Pulstar

I know! What's with the single digit, then bang up with the double

Oh right cool, a Denso IK24 would be ok then and slightly better than an IK22 without going too mad, maybe an IK27 is too cold for a car which is primarily used on the street (nipping to the shops) with the occasional drag run as it will get fouled up?

Ha! learnt something new, I've only ever used NGK.

Interesting you have an 11mm gap, but not the first time an 11 has been recomended over an 8 for boost applications.

Probably should have added that I manually gap them down to 0.7mm.

probably a good bit of insight

So Ben, what 'heat' number are those plugs?

Trying to source some Denso IK24's or equiv NKG's now, I can get a set of 6 off ebay for $105 delivered (they are in WA somewhere but prob not near me) but thought I would ring local first.
Supercheap - no
Repco can order NGK's in - at $32.99 each!
Anywhere else before I go with ebay?

I was able to get Bursons to get pretty close to the ebay price.

Just checked and there isn't one in WA - boo WA, Boo!

As I said before.

Hey we have sunday trading here now though you know, still no daylight saving yet as cows would be confused at milking time.

changing mine before tune as mine are starting to foul up esp since running so rich ATM, currently have NGK BKR6EIX-11 taking on board reccomendations should I stay with these (iridiums) or change to the above? Still going to run 7psi only (of course will replace more often now)
