Hey guys need some help on buying a good spark plug that is worth the money. Was looking at the TR55's but than I saw some called TR55IX and some called TR55GP... which ones would be worth the money im going to spend? Thanks....

 

delco iridiums here...theyre kinda expensive

 

just stick with the tr55.....

 

 

I sell the TR55's with a free set of MSD 8.5mm plug wires, ok its the other way around but you get the picture.. $65 delivered for MSD 8.5mm superconductor wires your choice of color red or black and NGK tr55 or TR6 plugs.
pm me if interested

 

forgot to ask these are new right?

 

Of course !

 

lol all i could think was, "I am sending that man my $16 for plugs and a free set of wires right now!" haha

 

ngk tr55s dumdumdum

 

^^So now LS1tech is getting spammed???

 

yep, what he said.

they will last longer then i will own the car. changed out the O.G.s at 105,000miles and they looked fine.

 

On my old TA(sold) I used Tr55 IX and taylors wires at the same time and notice a big differance in throttle responce. Went with a colder plug with this car and set-up.

 

i installed the TR55IX when the car had about 90K now its about to hit 160K so should i change them? Was wondering if it was worth spending the money again?.. if not ill just buy the wires from blancoSS
