Spark Plug Choices I'm going to be getting my car out of storage in a couple weeks and i decided that i want to change my plugs b/c i have +/- 40K miles on them. Everyone seems to say that the TR55's are great for stock N/A motors, and my motor is stock, i just have bolt ons.
I was curious about other options; my car currently has platiumn plugs in it (BOSCH) and i heard the TR55's are copper; isn't platiumn better? What about the irdiumn plugs?
My ignition is stock with the execption of MSD wires; i just want the strongest spark possible, but i don't want to spend $12 a plug if it will make zero difference.

Get either one of those and gap them to .050 and you'll be all set.
Spark plugs are one of those things that people just put too much thought into, especially with stock engines all the way up to 750 hp engines. There just isn't that much to them. You can spend $100 per plug and you will see zero difference in performance. Those so-called exotic plugs are complete bullshit. They are out there because there's a certain amount of years they will be able to screw the public with good marketing and make a ton of money selling them.

i agree the BOSCH are a waste of money; i didn't spend $12 on those, i was refereing to the Iridumn plugs; THOSE cost $12 a plug and promiss XY HP gain.
It just suprises me that a $2 plug seems to be what ppl use and get great results from. Is there any reason to go with another plug or is the whole platnium/iridumn thing just a marketing scheme?

Iridiums do absolutely NOTHING. Ricers and people who are just automotive idiots buy them. The word "iridium" just soubds cool.
Yes, TR55 or TR5 and gap them to .050. And don't let some cheese dick at the auto parts store talk you into using TR6's.

one last thing, what about those MSD blaster coil packs? Do they give you a better/stonger spark? Would i notice a difference using them? i heard that they tend to fail; did they change the design or are they a waste on money also? They're like $80 a coil pack btw...

Factory GM spark plug wires are all you need, and stock coil packs are good to way over 600 hp. $36.00 Advance Auto Parts spark plug wires are also just as good as factory GM spark plug wires.
Only way to get a stronger spark is to get a system that makes a stronger spark, coil packs don't make stronger sparks, they just carry whatever spark is given to them.

the above link is from NGK's website. They have the TR5's listed, but they also have a TR5GP. What is the deal with that one? Is that a better version of the TR5? Also, they're pre-gaped @ .040; do i still re-gap them @ .050?
The TR5 (V-power) is $1.99 per plug; the TR5GP (G-Power) is $3.59 per plug.
Like i said, the "G-Power" (TR5GP) is supposed to be a high-er performing TR5.

what is the point of re-gapping the factory gap of .040 to .050? What does this improve? Sorry if this is also a newb question, im just trying to get a better unstanding.

You want the V-Power plugs. Those GP's will do absolutely nothing by way of better performance.
Plugs are plugs. 100 years of design experience and they're still the same. These "so-called" special plugs are just marketing. They're trying to make money because as I said, plugs are plugs. They're trying to reinvent the wheel by telling people these new plugs are magical.
Gap them to .052 if you want to.

Ok; IF i ever get to the point of stroking, my motor so i can blow and spary it (
), i'd probably ask my tuner what plugs he recomemends. I can't see spending $10 a plug unless I'm told to for a specific reason. if the TR5's are good for you, then they will be fine for my stock internal, stock tuned, stock cubed/inducted LS1.
so what about re-gapping the factory gapped plugs to .050; what is the point of that?

ok, so how do you re-gap plugs? I KNOW how to check the gap, but no one ever showed me how to mess with the lead. the only way i can think of it using needle-nose plyers and prying the lead up to open the gap, and hitting it to close it. Somethine tells me that will break the electrode off the plug though. lol. If there a tool to gap plugs like there is to check the gap?
