Personally I'd fit whatever Jaguar say (and did on my car). They work really well...

 

The spark plug industry is much like the beer industry. Each wants to convince you that their product is superior to all others.

I have tried virtually every brand of plug on the market and found that the number of half-naked super models hanging around my swimming pool remains constant.

 

I use Denso: half naked super models were next door. He flies helicopters and is 40 years younger. He uses Densos too (he is a Toyota puke).

 

The stock NGK (2000-?) I think work really well, I put Bosch Iridium in mine, and it works pretty well, couldn't justify the $22.00ea for the stock NGK plugs vs the $8-$9 ea for the Bosch ones.

 

I just changed my plug yesterday NGK Iridium

 

Vincent,

Which NGK Iridium plugs did you use? What specific car do you have?
