Hi,

Due to bad idle and exhaust firing recently on my BA XR6T, it's time for me to change spark plugs and coil packs (as suggested by many members on this forum). How do I know if it's a spark plugs or coil packs problems? I am gonna change one by one to see. I am gonna change the spark plugs first as they're cheaper.

I haven't changed the spark plugs since bought the car at 100,000kms (now it's done 175,000kms), so I don't know which spark plugs is good for the BA XR6T? My tuner did regapped my spark plugs when he tuned my car (but I forgot to how much the new gaping is, does this really matter to chose the spark plugs)

Any suggestion on which brand and product number of spark plugs should be used on my car will be appreciated (there're a few platinum one on the market so I don't know which one is good).

The platinum spark plugs should last for 100,000 kms, is this correct?

Hey mate, grab the NGK PFR6B spark plugs as they are platinums and already come gapped at .8mm. I and a few mates have these and have had no problems,they are a wrx plug and are a perfect replacement for the ford ones.

Thanks for your information. I'll get the plugs soon and put on my car. However, I've just opened my bonnet and couldn't find where the spark plugs on my BA XR6T is (sorry for asking such a stupid question, but I've never changed the spark plugs in my car before so I don't know. I did change it on my previous cars the plugs were just there in front of me when the bonnet was opened). Do I have to open the engine cover to change the spark plugs on the BA? Is it easy to do?

mate I used PFR7B ngk's and its stopped my spitting problem I encounted after my last tune and they are already gapped. there is a thread on here how to change spark plugs. click here it will show u a step by step how to change them

Just a quick tip, when I replaced mine I paid like $18/plug and found the same ones on E-bay for $13 each so have a shop around before you get them

part number is bkr6ix NGK iridiums make sure u dont get the ones with number 11 on the end of the part number....watch out for the ones on ebay some of them state they are good for unmodified cars but your car is tuned so wont be much good to u. And another thing they might last 100,000km on a normal car but mine lasted about 20,000km before they gave up.

the best ones seem to be Denso plugs. do a seller search on ebay for "btpartsspecialist1" he has .8mm factory gapped plugs suitable for xr6t. he runs them on his own.

platinum plugs are the go as well as regular servicing

I just changed mine, got the standard ford iridiums, for $10 each from Coventrys in os pk Perth, bargain.

NGK copper v-groove are about 3.50 each. Check the gaps before fitting them.
