This topic is pretty much all about preference, some will say stick with AC Delco stuff as its wat came with the car. The choice is made harder because of all the new types of plugs. I seen a spark plug tester setup by NGK, comparing there iridium fine tip plug to a standard thick tip. What i saw when i pressed the button was a single bright blue spark jumpin the gap of the fine tip, and for the standard tip it wasnt as bright and there was tiny sparks all over the bigger tip. Denso makes the finest tip at 0.5mm i believe, said to be the best plugs money can buy. As for wires, ive got a set of Taylors on order, a good site to read about electricity and wires and real facts is
http://www.magnecor.com/
they make good wires, but i couldnt find a supplier around here, and im not ordering anything over the boarder anymore, to much extra tax charges and garbage.
This is a good question answered on the site
5. How much extra horsepower can I expect when I fit Magnecor Race Wires ?
Professional race engine preparers do not use Magnecor Race Wires to increase engine horsepower — they use them to maintain full engine horsepower. Often, production vehicle owners comment that engine performance increased after they fitted Magnecor Race Wires, and most owners of modified vehicles find that horsepower increases during a dyno test — however, in reality, performance increases because the engine's potential power was previously restrained by:
(1) Failing conductors in original equipment ignition wires;
(2) Failing conductors in aftermarket carbon conductor and European and Japanese spiral conductor ignition wires;
(3) Failing resistor-connectors on German ignition wires;
(4) Aftermarket spiral "low-resistance" and "super conductor" ignition wires interfering with the engine's electronics;
(5) So-called "built-in capacitor" ignition wires inducing too much available current to ground straps and interfering with the engine's electronics.
Despite what is published in advertisements and some vested interest magazine articles, no spark plug wires will generate or "install" additional horsepower. However, a decrease in horsepower will occur if the wires' conductors fail to conduct the spark energy needed to fire spark plug gaps, or EMI emitted from spark plug wires causes the engine management computer to react abnormally, or so much spark energy is lost into the ground straps of so-called "built-in capacitor" wires that little is left to fire the spark plug gaps — see test in Circle Track Magazine (USA), May, 1996 issue. For these reasons, Magnecor Race Wires are used by many successful race teams and individuals all over the world to eliminate the risk of such events occurring
