Spark plug NGK or Autolite
Oil change every 5-7k miles Mobile 1 European Formula (0w-40) Seafoam every 5-6 months New NGK Laser Platinums Plugs (500mi ago) 1 new coil
I run the DCPR8EIX and they are great. No need for 9's for me.
NGK are a good spark plug brand.
NGK plugs have never failed me at my shop. I'm pretty sure they're NGK 3199 plugs
i changed the plugs out for oem replacement NGK plugs (it had bosch platimun +2 in it) and a set of wires. and it ran just fine it was fixed. i then decided to swap my other coilpack back in and it ran fine no issues at all.
I put in NGK PFR7B plugs and R8 coil packs. Smoothed the idle out and judging by the butt dyno the rev/boost response seems great.
I run stock NGK with .026 gap as well and I've been anywhere from 10-18psi
NGK BKR7EIX is a popular plug for 1.8T and 2.0T, but it is one step colder in the heat range. Fine for those whom don't see freezing and below temps.
I used the NGK plugs once and kept getting a pretty bad hiccup under hard acceleration.
My car started experiencing misfires after changing the sparkplugs. Never happened before. Now it gives me a code for random misfires and #4 in particular. Today is the second tome it happened after starting the car on a cold morning. Second time 2 weeks after changing spark plugs. Just after I start, when its still cold, and never during driving or idling when warmed up. Strange. Could it be the plugs. I am using the new NGK ones. NGK Part # 1675 Laser Platinum pre gapped. Didnt have a problem with this before. I think these a are one range colder than the previous ones I had in the car. Could that be the problem?
