What Spark Plugs Grade Should I Use?

[javier.abraham]

Hey guys i'm running the following and i want to know what Grade of Spark Plugs should i use, i've been running with NGK V-Power Heat Grade 8 but i don't know if these are the proper one:

Apexi S-AFC 2
Denso 255lph Fuel Pump
HKS FCD set @ 6
Downpipe
2.5in Full Exhaust
Fuel Pressure Regulator
Hallman Boost Controller
FMIC
Oil Catch Can
Running 130HP @ 12 PSI

Also take note that i live in the Caribbean so it's always hot here, the average is 90Farenheit or 32Celsius.

heat range 5 plugs,,if yours one are grade 8 if that means heat range 8 there to cold a plug for your power

First time i changed them i put Iridium Heat Range 5 but after 3 months they were roasted.

mybe try heat range 6 .but 5s should be ok with that power?

Thanks mate...I was thinking Heat Range 7. A couple of friends are using 6 on their stock ones.

Heat range 7 should be fine, thats what i would use if near 200bhp but considering the heat & your 5's where toasted, i would go 6-7 max

Iridium or V Power?

Lately i'm seeing better results with VPower

Id say Iridium but again its hard to comment as we use these plugs in a different temperature climate.

Do you agree with 6 or 7?

 

[Iain@CRD]

If VPower works well then stick to works best for you ofcourse mate.

6 or 7 seems about correct yes for your climate.

Do you agree with 6 or 7?

7's minimum in that heat, certainly no lower

are you using a stock turbo? If you are why the hks fcd and apexi are being used?

Yes im on the Stock Turbo. Without the FCD i hit Fuel Cut and the Apexi i basically wanted one but im about to sell it, since im not getting much result and im only getting 250km for the whole tank, ive taken it for someone to tune it and he has done it twice and made me 2 setups, one for driving calmy and another one for racing...You can feel the difference but i find weird that with both the fuel consumption is the same...25km per gallon.
