Hello everyone...Spark question for you

[nitr0j0e]

I have a 99WS6 and I am curious if anyone has the Granatelli Spark plug wires installed on their LS1. I already have the Granatelli Air box, K&N air filter, Hypertech Stage III chip, and Borla exhaust. I heard that the new plug wires would make a difference in fuel economy and horsepower and was wondering if the gains would justify the cost.

i'd rather spend my money on other crap... i still have the stockers on mine...

[Mr. Luos]

Gains do not justify cost.

The design of the coil on plug means there is such a small distance for the spark to travel, it doesn't matter on most cars.
Now, they would be worth it if you had a shitton of power.


How did you 'chip' the car?

Hypertech Stage III tuner......really not a chip but a reprogrammer.

Camaro Spark Plug Wire Set, LS1, Granatelli, 1998-2002


Adds Up To 15 Rear Wheel Horsepower
0 Ohms Resistance & Computer Safe
Increases Power To The Spark Plug Up To 400% Over Stock

[Mr. Luos]

Lots of places have claims that don't exist on a regular car.

The ONLY way they add 15RWHP is if the stockers aren't keeping up with a 750RWHP car.
On a near stock car, at most, 1-2 RWHP, if that.

Well I know that everyone makes their claims to sell their product. I have over 80k miles on the car now and I am noticing a miss that is probably plug or plug wire related. Thought about upgrading to lower resistance wires to pick up the performance a little over stock wires. Haven't found anyone yet that has these wires on their car. Even a 5RWHP gain for $200 dollars is not too bad.

[Mr. Luos]

How much are those wires?

I have heard good things about them from people with high horsepower cars.
I personally would leave the stockers. They shouldn't be a problem.

[nitr0j0e]

They list for $210 at Summitracing.com

[Mr. Luos]

Ouch.

The MSD ones are similiar in performance and should be around $75.
MSD are the ones I would get if I were going to upgrade.

Appreciate your help. I will have to see what the budget will allow and decide from there........
