Spark plug NGK or Denso

Atualmente uso velas e bobina NGK. Perfeitas.

I’ve been a Toyota certified master diagnostic tech for nearly 30 years. I can tell you that I’ve seen Toyotas come in running poorly and all we do is scrap the off brand plugs with either NGK or Nippondenso and the car runs fine again.

Based on your parts list, I'd recommend getting the Denso or Hyundai branded ignition coil. Denso is the OEM for Hyundai. For spark plug, get the NGK 9723. These are the OE spark plug for Hyundai.

I've had misfiring when I installed it dry and torqued to spec on my Civic 8 gen. No misfiring after anti seize...

Just changed the plugs on mine @ 75k 2 weeks ago. DIY EASY! Installed the NGK Laser Iridium ILKAR7L11 94124 plugs. Old ones screwed right out.

I change spark plugs - I change my plugs every 30,000 miles spend the extra money for NGK.

I was running APR coils and went back to OEM. That helped. So did going to the Denso 5750 plug and getting an EQT grounding kit.

Only ever buy ngk plugs and learn to read their reference chart then you will always know what plugs you can/can't use for small engines

My 2010 came with denso, replaced them with ngk at 100k, then at 200k replaced them with denso…not sure if it made a difference

I had EPC light/limp mode and P303 as well about a month ago on my '12 GLI (APR Stage 1+) at 102K miles that recently had a walnut blast and new Denso plugs at around 101K miles. Swapped coil packs as well and still P303 with EPC light/limp mode.
