Plugs and wires???
 

I need to know what spark plugs and wires I should use to do a tune-up on my car. I've seen similar questions asked, but it's always on modified engines (mine is stock). What else should I change when doing a tune-up?

Any help greatly appreciated...

taylor spiro-pro 8mm wires specifically for the LT1 = $50

NGK tr-55 plugs = $2 each

nice and simple...

do a search and you'll see some tips on how to make the plug change go much smoother...


oh and as for what else to change...depends on milage and what you feel like changing...

fuel filter, differential gear lube, tranny fluid, radiator flush, front o2 sensors, and maybe seafoam the engine

I have 90,000 mi on my ride. The radiator fluid is pretty new. How easy is it to to a fuel filter? I've never done one on any car.

Its as easy as the oil filter really. Some needle nose pliers are all you need I think. Just release your fuel pressure by removing gas cap and depress schrader valve with a screwdriver (wrap a rag around it to catch the fuel that will spray) then remove the fuel filter (on the driver side, near the rear tire) and install the new one.

go with acdelco plat. plugs, and order a set of the accel 9000 wires, they are already made, just slap them on...make sure you silicon the hell outta them. i did plugs, and just did my wires, and it was like giving a 90 yr old man viagra, plus you can almost lay them bad boys on the manifold and they wont burn! :cool:

How do the NGK plugs, Boush platinums,and ACDelco plugs compare to one another?

ive had good results with champions, and they are cheap:) I got them for 1.29 a piece.

I got NGKs, and I like them. To me, a plug is a plug. I would stay away from the platinum plugs and all the hoopla (yeah I know the stock plugs are platinum, so what? Its just for longevity). If you can get AC Delco non-platinum, NGK, Champion, Autolite, they're all pretty much the same. NGK seems to be a cut above the others.

MSD
 

I'd go with MSD wires and NGK plugs. Ive had great luck with them in the past. Someone should do a resistance study on wires, cuz i know that MSD claims the lowest resistance per foot on their plug wires, but who really knows, id like to see how they stand up to the Taylor's and etc as far as ohms per foot, anyone know?

CR

for the record the Spiro-pros are cut to lenght already too, no need for crimping or anything...

and they fit in stock wire looms (can be helpful) and are inexpensive

i wouldn't waste money on plat plugs...at $2 each for NGK, you can replace them 3 times for the price of a set of plats...and once you know how to do the plugs, it can be a very quick 1 hour job...

plats aren't worth it to me...

I went with MSD SuperConductor 8.5mm wires ($90 from my local speed shop). They had a display set up with 8 different brands of wire, you selected which wire to test via a dial, and then pressed a 'test' button and it activated the large ohmmeter on the display. From what I saw, the MSD's did indeed show the lowest resistance per foot (I want to say in the neighborhood of 50 ohms, if that isn't too outrageous). As for plugs, I went with AC Delco platinums, and love them. Just be warned - if you go with wires larger than 7.5mm, you're probably going to have to ditch your stock wire looms. It's no major catastrophe - I ziptied my MSD's away from the manifolds, and it's been fine for almost 2 weeks now.

As for other things to change during a tuneup, when I did my tune up, I seafoamed my engine, motorflushed my crankcase (which I won't do again - my brother, GM master performance powertrain tech extraordinaire says that fast-acting solvent cleaners are the devil for high mileage engines), changed my oil to castrol GTX high mileage 10w30, replaced my oil filter, PCV valve, and fuel filter. I also cleaned out my MAF and used Seafoam Deep Creep on my Throttle body. All in all, My car went from acting like a 1994 with 90k miles to a brand new ride. Idle, power, everything, it's all like brand new now. Good luck with your tuneup. If you're planning on doing it yourself, watch out for breaking the bolts on your manifold when you remove the Y-pipe. I'm the proud owner of 2 broken bolts, 1 from each manifold. Fortunately, my leak isn't all that bad, but I'll be replacing them very soon.

I'd go with the Accels and TR55's. I absolutely despise MSD wires. I've worked on 3-4 cars with them and ALWAYS ended up with a bad one, either due to defects or heat damage with headers. Can't always blame that on the wire, but never had that problem with an Accel. Just a week ago we found a brand new intermittent MSD one. YMMV,

after pulling my bosche platinums out and looking and them wondering where the hell the electrode went ill never run them again. just look like the center sunk in. i went ngk tr55's and accell 9000's

On a stock car I would say MSD Wires being that they have the lowest Ohms per foot of any wire out there and NGK iridium plugs being that it seems they are the best plugs.
