Spark plug Bosch or NGK

I run BKR8EIX gapped at 0.028 with great success as my regular plug.

bkr7e for pump gas.

Dave is right, I checked mine out of the box with wire guage. .030" the same as stock ones I removed. From the box to the car no adjustment, no misfires, runs great.

i have been using the W7DTC plugs and they have been working great for me..my car is always held way up in the rpms..they have never fouled out or caused me any problems..and i get 8 of them for 30 CDN... seat of the pants tells me i like them better than my old platnums..the car idles better with them.. they are worth a try

I've been running W7DTC's for about a year now, with no problems. I haven't done any back-to-back dyno testing to see the difference between them and the usual W7DC's, so I can't comment on any power losses/gains.

Change the spark plugs every 20k and use OEM NGK plugs. They work the best for our cars. I\u2019ve run Bosch Platinum +4 with no trouble but the NGK seem to work the best for me.

oh i have an APR chip, N75 H valve, GHL CAI, forge turbo inlet pipe, evo ms diverter, ngk spark plugs (the smaller gap ones for chipped cars...one range colder) its also insanely cold outside now...havent diven with these mods in the cold yet....should i try the N75 J for the winter??

Gap them to 0.028 and buy NGK BKR5EKUP platinum (change around 40,000miles) or BKR5EKU for the coppers (change around 15,000 to 20,000miles), don't use any other plugs they aren't as good!

They have 2 electrode and yttrium content with copper core. First, the car idle better now than with USED NGK 3 prong spark plug.The idle is lower at 800rpm(new spark plu gap) compared to 920 with NGK (bigger gap) The stock spark plugs were hafl used, white-black color but with some yellow tiny dots on electrode surface whats this ???? I went for a run and these spark plug are not made for high rpm use.. The engine noise is metallic above 4k and it doesnt pull like used but in shape NGK plugs. The spark plug gap is too small I think. I will check my mpg and report this later.

I was running the bkr7e, but I fouled two of them in 1000 miles
