Best Spark plugs for JB4,DCI, and downpipes?

335inYEG · 03-08-2015, 06:25 AM

Best Spark plugs for JB4 either map 1 or 2, DCI, and 3" catless downpipes?
in the future looking at a FMIC.
Comparing the OEM replacements to the NGK 1 step colder plugs.

any feedback would be great!

OEM work just fine and last longer. You can save a few dollars with NGK 5992 but you need to gap them yourself and supposedly they don't last as long.

Stick with OEM

Oem. Colder plugs don't seem to run as well at low temps.

I'm running 5992 oem were definitely running too hot now the car runs perfect. Just curious how many of you actually have run them that commented above?

I just purchased oem from advanced auto parts and used a $40 off of $100 coupon code I found online and they came out to $63, that plus 2 cleaning products (you get free shipping over $75) was a great deal.

I've been running the 5992 gapped at 0.028 or 7mm for almost 20k and never had any issues with them at all during cold or hot times. When it was - 15 in Chicago car started up perfectly fine. Only think is gotta replace them every 8k
