Those are not NGK Laser Iridium SIKR9A7, which are the plugs spec'd for use in the car. Regardless if the plugs need to be changed after only 2000 km of use, you have a bigger problem. Or was that a typo, and you meant you put 20,000 km on them? If it's 20,000 km, then that's about half the normal duration they specify, but they do state that you should change them every three years regardless of how many kilometers you put on them. Personally, I swap mine out every 25,000 km... or 3 years... whichever comes first. If you're running a tune, then they're obviously gapped tighter and will wear faster as well.

Here's the link to a great article on this website that speaks to plug specs. https://www.124spider.org/threads/spark-plugs-they-are-not-all-the-same.43865/

 

Nope, I think he meant 2000km because otherwise he made the same error on the belt mileage.

As you say, plugs kaput after 2k miles means somethin' aint right!

 

2000km is a very short interval. The pics are blurry so we can’t tell. Denso is a reputable manufacturer, but if I can get the exact item specified, that’s what I use. NGK is an EU brand and ought to be very easy to find. I don’t argue with the engineers.

Wrong plugs were used. The OEM plug, which there is virtually no flexibility on, is NGK SIKR9A7. People have tried alternatives and nothing works as well.

And no, you can't say "But they worked fine", because they didn't - they only lasted 2000 km.

It looks like you replaced the old wrong plugs with new wrong plugs. Those need to come out promptly and be replaced with the correct ones.

It is a 100% requirement on this engine to use the NGK SIKR9A7. The NGK will last you 50000 km.

(EDIT: Even if you meant 20,000 km not 2,000, that's still too early. Put in the correct plugs!)

 

just asking, what about plug wires? I've little experience but know of a case where wrong plugs AND wires were used and they were replaced over and over until it was "figured out". that's been 30+ years ago on a turbo engine.

 

Hi Guys,

Yes, I meant 2000 Km.

I just ordered them online.

They will be replaced once the correct ones arrive.

Many thanks for your feedback

 

I just ordered them online.

Hopefully from a reputable dealer. Theres huge amounts of counterfeit NGK's out there. I was nervous about buying mine from Rock Auto in the USA (I'm in the UK) but I'm convinced they are genuine. Actually, I need to order a couple more sets.

 

These guys are legit.

Since Brexit, we are experiencing huge difficulties purchasing staff online from the UK. Much more expensive and takes ages to arrive

Coincidentally, we in the US are having the same problem with the entire rest of the world! Fancy that!

what's the fifth picture

 

You mean the multiair filter?

 

There are no wires. The coils sit directly atop the spark plugs like most modern engines.

 

😍🤪🤣 doh!
