Wires
taylor,msd,ac delco?

Plugs
ngk,ac delco, autolite 104's?



any other parts that I need to replace when reached high mileage?

I like using the AC Delco platnuim plugs and wires. They will go 100k.

Magnecore wires seem to be noted as the best. Had good luck with mine on the caddy. I like the Taylors too, but only if you are not running headers. The boots at the plug are too big and could cause interference issues.

NGK TR-55 copper plugs seem to be the most recommended plug in cyberspace, too. I've had good luckwih them. But you will have to swap them out once a year or so. Otherwise, I would run regular Bosch Platinums. The single platinum. I run those in the marshmallow. I like them because I get good life out of them and I don't have to worry about the platinum "pucks" coming off like on some of the other brands.

I cannot backup Crovo on the Bosch plugs...

All I've ever heard from anybody else is that Bosch ignition or 02 Sensor products do NOT work with much success on our cars.

Maybe Crovo is the aberration, but I would never buy or install Bosch plugs or wires.

The NGK TR55's on the other hand are great plugs. I had them in my wagon. They are not a long term plug tho.

I used the Delco Platinums and Delco wires on my Sedan and they held up great for years. Somewhat more expensive though.

the A/C Delco wires go for over $140 I had no problems with MSD wires

I had a set of MSD pre-cut wires on my TBI Blazer and they were terrible! They physically fell apart, before that, the boots wouldn't go onto the plugs/click unless you put a ton of dielectric grease on them (ridiculous fix that MSD instructed) and then they'd still pop off. Fortunately I was able to sell them on craigslist to a guy that was going to modify them for something else. I don't have anything bad to say about their other products though, I hate the damn wires.

I use Napa Belden wires, I used to use the Delcos but last box of them I got said "Made in China" on it! I've always used Delco plugs though. I don't know about the LT1s, but on the TBI cars, Bosch has always been considered a no-no when it came up for discussion on other forums I'm on, just like Fishah said. I think the Delcos are more in tune to the engines.

THANKS GUYS

I STILL DNT KNOW WHICH ONES IM GOING TO GO WITH

I just use the Duralast wires from Autozone. They work fine and when I do a tune-up I can just bring them back and exchange them for new ones for free.

As far as plugs go I end up getting the Delco's from Autozone, and you can return them every year too.

I have the Taylor 8.5 spiral steel wires and autolite 103 plugs from my needs

I think I got mine direct from Magnecore.

I've read that the ac delco plugs are the best to use. I have them in my caprice with msd wires. Never had a problem and I drive my car, super hard, every day.
