Hi guys I tried searching but I can't find a good recommendation.

I have a 1998 eclipse N/T with 131,000 miles and minor mods including

full exhaust / headers
cold air
no cat

and i'm about to purchase Nitrous (kit from NoS) so please recommend which spark plugs would be best for a NoS setup. Please keep in mind I'm not sure yet if I'll be going with wet or direct port, but it definitely won't be dry.

I plan to run a 35 - 55 shop on it so please recommend me the best, $ is not an issue when it comes to my car.

Thanks for all opinions

edit: so I just did some research and found these

What do you guys think about this:

The Spark Plug
Serious Enthusiasts Rely On

Designed specifically for the performance enthusiast. Iridium IX® offers extreme ignitability, improved throttle response and superior anti fouling
Fine Iridium tip ensures high durability and a consistently stable spark
Iridium alloy has extremely high melting point, perfect for today's high-tech, high-performance engines
Trivalent Metal Plating - superior anti-corrosion and anti-seizing properties
Outstanding acceleration, high fuel efficiency and durability
Ultimate design, technology and performance.

I know everyone says NGk is the best right?

NGK BKR-6 for non-turbo, gapped to .045ish
NGK BKR-7 for turbo, gapped to .028-.030

I use Bosch plugs just because the NGK's are somewhat more difficult to find. They're just their basic copper plug, though... very similar to the NGK's. OP, I wouldn't recommend any of those "premium" plugs, like the multi-point or iridium's. There are a lot of reasons not to use them, so I won't reiterate them here, just do a search.

Though you didn't ask, I use Granatelli spark plug wires. I can't honestly say I've noticed any improvement in performance using them, though. You would probably be just as well off using a new set of OEM wires. Any claim that a spark plug wire makes a noticeable difference in power is bogus.

NGK G-Powers...cheap, extremely reliable, good for any setup, available at Autozone for under 12 bucks (for the set of 4). I will never go with any other brand of plug than NGK, they have NEVER failed me.

Thanks for all the help guys. I went with the NGK iridium's and when I went to pull out my old plugs I noticed they was a little black stuff on there. They were NGK's tho so they took the beating LOL
