Hello

Iam sitting here and order parts for my service on my GP T-jet

In the manual it says that you should replace your spark plugs every 1year or 30.000km

I have never heart that u should replace the spark plugs that often. I found out those spark plugs that is sitting in the T-jet engine is some special Irdium plugs

What do you think, how often should i replace

Morten

if thats what the manual says.....!

Yep it is what the manual says

The manual doesnt state that they should b replaced every year. It says every 30K km
According to quite a few t-jet spark plugs i have seen at about 30K, i wouldnt say that they seem that bad ie they could last longer.
Have a check at the 30K service and according to their condition replace/keep them.

Personally for the sake of £20 I'd do it, just to maintain performance and fuel economy.

My 1.4 16v uses the special plugs too.

Still 20 pounds x 4 if they can last longer.

I know from previous cars that platin spark plugs could last 100.000km

Okay, it make sense check and replace if req

Mine kills sparks after about 14k.

Especially when you start tuning.

PS 14k miles i suppose?

Yeah we go by miles in the UK.

30,000km = 18,641 miles.... or 18,000 miles in the world of Fiat UK servicing.

The T-jet plugs are really sensitive, and suffer from flooding easily. We've had numerous cases where a new car has been driven off the transporter, switched-off, then refused to restart 5 mins later.

Changed mine at 22,000 miles they looked like they could take another 10,000 or so but from shop4parts it was about £40 if i remember rightly so worth it when doing a service

Those we have in stock can be done for £42.50 inc VAT and post for a set of 4.

But at that price once they are gone they are gone!!

Hey Guys

I have a grande punto 1.4 TJET 2009 (59 plate) and was wondering if anyone new the GAP size for the spark plugs?

thanks

NGK recommend the IKR9J8 now I think (as per here: http://www.ngkpartfinder.co.uk/car_commercial_extra.php?id=12395) which have superceded the IKR9F8


My understanding is that they're gapped at 0.8mm though I can't see that listed formally anywhere
