Plugs and gap

[Jordan83]

Hi All, I am just wanting suggestions on plugs and gap settings?  The car is 401rwkw.  Cheers

stock factory ford plugs gapped to 0.8mm

Cheers, will this give me that balance between cruising and under load? The problem has been a missfire at cruising speeds..

sounds like your tuner needs to clean up the cruising part of your tune... it should not misfire on cruise as there's almost always no boost.

AGSP22YE07’s , don’t gap plugs when you can buy Genuine ford plugs at 0.7mm gap Perfect for stock-500rwkw @ 22 psi

 

sounds like you tuner needs to scale injectors better “IF” your plugs/coils/02 sensor are all good

@JETURBO, Hi, are you saying the standard xr6 turbo sparkplug which is 6 heat range is fine for up to 22psi boost? Im going to run 18psi and about 350rwkw and I thought 1 heat range colder would be needed. Is it not necessary to go to colder plugs on these motors??? Thanks

What jet quoted is the gas motor plug, not the turbo plug

 

arronm do your link thang....

Thanks camo, so should I go 1 colder heat range to a 7?

[arronm]

No, what plugs are you using?

 

I buy these which are 20 heat range 22 is slightly colder, but when you open the packet the plug inside is AGSP22YE07’s. Used multiple sets but only noticed last time I installed a set.

I have stock standard plugs in it at moment, iv just been stock piling parts and I'm about to start the big monster garage project soon, Ford over here said they cant get 1 heat range colder, repco said $56 per plug for 1 heat range colder iridium, but that sounds way too much $. No one in nz seems very helpful so far.
