tiggz54 Posted March 20, 2008 Report Share Posted March 20, 2008 i'm considering upgrading my spark plug wires and was wondering how much of a difference they would make. should i keep the same size at 8.5mm, what brand, is it even worth it? (i only have a few bolt ons so i figure every little bit helps) thanks guys! Quote Link to comment Share on other sites More sharing options...
packjh Posted March 20, 2008 Report Share Posted March 20, 2008 hmm the trust worth seat of the pants dyno says no real gain... But who says having less resistant spart plug wires is a bad thing?? most common brand used is MSD since its so popular i thinking about swapping out to taylor to just give them a try its almost time for a wire and plug change anyway.

Hankg42 Posted March 20, 2008 Report Share Posted March 20, 2008 MSD Part number for our trucks is 32829. Got mine at http://www.summitracing.com/ Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted March 20, 2008 Report Share Posted March 20, 2008 No real HP or seat of the pants gain, but bigger wires provide a cleaner, hotter spark to the plugs with less resistance, which means more efficiency.........the stock wires have 1000 ohm per foot resistance while the MSDs only have 45 ohm per foot resistance. Definitely a worth while upgrade. Quote Link to comment Share on other sites More sharing options...

thunder550 Posted March 20, 2008 Report Share Posted March 20, 2008 no horse power gains off of plug wires, GM did a real good job on the stock wires, coils on all the LSx motors x2....don't waste your money unless your existing plug wires are bad and you can replace them with aftermarket ones for cheaper than stock.

smoke03 Posted March 20, 2008 Report Share Posted March 20, 2008 I have a wheatley tune and I really like it. He has great customer service. As far as the wires, I pulled my stockers off and measured them with an Multimeter and there right at 1000 ohms each.... the new MSD's look alot cooler than the stockers Quote Link to comment Share on other sites More sharing options...
Badkarma Posted March 21, 2008 Report Share Posted March 21, 2008 I duh know, I just switched mine out for the hell of it * and to go with my engine covers that are being painted chevy orange* and I noticed thsy smoothed things out alot. alot smoother at idle, dosnt have the ruffness *technical term* that it used to, and acceleration is alot smoother. Plus the 940-1000 ohms or resistance for the stock wires with just sad Now I just need some shiney headers lol. Quote Link to comment Share on other sites More sharing options...
