Spark plug NGK or Denso

I changed

- 4 new NGK Iridium sparkplugs

Now post how much they want to change spark plugs. I've usually seen dealers asking for $200-$250 on a 4 banger. Or I can buy some nice NGK plugs for under $60 and get them changed within my lunch hour in the parking lot.

I run NGK Rutheniums now and they've been excellent handling 30psi of boost with zero blowout even at wider than the .024" gaps that most tuners recommend. Oh and theyre MUCH cheaper at $8/ea vs $40/ea for the NGK race plugs.

I went to colder plugs from ngk and noticed a difference in shift pattern for the better (my car is an auto).

OEM plugs are NGK as well.

I changed my plugs recently and qent with NGK Ruthenium gaped a step colder and they are working well for me, seem better than Motorcraft but thats just my opinion.

I just did the 30k service and my mechanic recommended these plugs. They are expensive, but worth it.

I'm running NGK Iridium NGK LTR71X-II 1 step colder but I am tuned. Been running these sparkplugs since the car had 5000 km. I have 45000 km now in 8 years and a half and I have changed 3 sets as it is recommended to change them a bit sooner than 30000 km on a tuned car.

That gap is INSANE, or at least appears to be.

In case you were wondering why those plugs look different, that plug on the left you’ve chosen (BKR5EIX11) is a plug that doesn’t match the longevity characteristics that Nissan originally set. The electrode basically isn’t designed to last as long.

only buy ngk rest is shit
