Atualmente uso velas e bobina NGK. Perfeitas.
I have a shelf of new parts for a bunch of my VW’s. All the cap and rotor parts I can find are the same for either car. They’re brand new. The plugs are brand new as well. Gapped by the Bentley. The plugs were “black” from trying to fire but not.
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.
I purchased from a local auto parts store for my 07 E550 and SO's 05 E55 - stealership quoted around $1k, parts for each with Bosch Iridium plugs was about $125. Installed new plugs at around 70k for the E550 and OE plugs (also Bosch) looked clean and the gaps were spot-on
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 noticed a slight miss at while cruising between 67 and 70mph. I ran VCDS logs and found misfires on cylinders 3 and 4. Imagine my surprise when I pulled the plug for cylinder 3… no signs of any other damage and I have no idea how long it’s been like this. Never got a CEL.
I installed the new NGK Ruthenium HX plugs and so far everything has been great ????
Bought these exact plugs recently and had the same problem- tip doesn’t unscrew- had to return them.
Champion is OEM and what we suggest at work, but NGK has never failed us with any application. Bosch is generally terrible and we only use them if it’s a very specific application.
