Spark plug Bosch or NGK

I changed

- 4 new NGK Iridium sparkplugs

My 2017 VW Jetta 1.4 5M - at 67760 miles on the factory original plugs - now has new Bosch Iridium/Plattinum plugs - (YA5KIP80)..................(the only symptom on the old plugs was a MPG drop - no hard starting, no missing, no rough idle......... EZ

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.

buy original. or atleast bosch, they are OEM-quality

these BRISK ones are cat in a bag

I have installed brand new NGK sparkplugs and Bosh ignition coils...but the cylinder 1 misfire does not move or is resolved at all.

Get rid of those ASAP. These are prone to breaking their ground straps. Myself and many many others have fell victim to this.
