best spark plugs to buy for the rx8
 

need to replace my spark plugs cuz i think they may be the reason why my car isnt turning on right away. every time i turn the key it sits there a couple seconds before it turns over, so figured a good place to start would be with the spark plugs.

from what i can see a lot of people are going with NGK Laser Iridium Spark Plugs, are these the best ones to get??

any input would be cool. :wiggle: thanks

Are you saying when you turn the key , there is a delay to the starter turning over, or that the motor turns over but takes a few seconds to fire ?

I use the NGK in my NA application (FI requires a 'cooler' RX-7 type plug).

NGK Racing plug 6700 RE7CL .048 Leading $20.55 (L = Leading)
NGK Racing plug 6701 RE9BT .048 Trailing $20.55 (T = Trailing)

Above from sparkplugs.com, although BHR here often has better prices.

ya i turn the key and it turns over but takes a few seconds to fire

Yea id ask BHR before anything.

Real im digging the headlights, those are intense. You should pm me how you did that so i dont s**t on your thread.

Did you ever fix the issue? My rx8 does the exact same thing.

LOL you just bumped a 3 year old thread

I wonder if the OP is still around

edit:
There are quite a few items that can cause hard starts
Coils
Plugs
Clogged Cat
Low Compression
Worn out starter or using the old model starter from the 04-05's

Just to name a few

get a new starter, problems solved.
