so i gotta replace the fuel injectors. the dealer hydrolocked the engine with fuel and wont cover it so i hope there isnt a bent rod. but...what plugs do i replace with? it is a 92 lt1 six speed.

thanks

 

NGK tr6

 

Never tried NGK but have heard good things about them. I use ACDelco RapidFire plugs. Stay away from the Bosch especially the +123 & 4. Unless you are heavily moddified, going all taht extra mile with the miracle spark plug is going to be a waste.

 

Ngk tr55

 

NGK TR55 or AC/Delco. And for fuel injectors, contact FICINJECTORS here on the forum. His name is Jon, he's great. or go to www.fuelinjectorconnection.com . He'll get you exactly what you need, for cheap, and even give you installation help over the phone!

 

Wow... presume you've contacted the regional service rep ... ouch..

RE: plugs -- OEM is ACDelco platinum. However, because ACDelco doesn't make an iridium for our LT1 engines, and I had 3 ACDelco platinum plugs which had lost their 'pucks' (small platinum spot on the inside of the ground electrode).

Because of this, I choose to put in NGK TR55ix (iridium) in our 94 -- Been running good.

BTW, remember to use a torque wrench and a dab of anti-sieze.

 

sry ill be running tr6 since im gonna shoot a shot of juice but tr55 is fine for a driver
but if you want to spray 100+ then tr6 gapped .035 is the way to go
my local tuner swears by them in all his turbo/nitrous builds

 

also, be sure to buy a gapping tool and gap ALL the plugs yourself to 0.050". The AC/Delcos, at least, are supposed to come pre-gapped, but I had several that apparently got bumped during shipping, and were WAY smaller than 0.050"

 

NGK TR-55 Double Platinum.
