CraigW Posted October 23, 2005 Report Share Posted October 23, 2005 When you installed your new spark plug wires did you put the aluminum sheilds that are on the stock wires back on or leave them off??????? Thanks Link to comment Share on other sites More sharing options...
XGMTech Posted October 23, 2005 Report Share Posted October 23, 2005 I left mine off when I put on my MSD's. If I have any problems later on, I can always put on those heat shields for the boots that they make. Link to comment Share on other sites More sharing options...
mwalls54 Posted October 24, 2005 Report Share Posted October 24, 2005 I have left mine off. I have been running them with out for about 4 years now. 2 and half years on the ss and year and half on 2001 Z71 and never had a problem. Link to comment Share on other sites More sharing options...

sandmanss Posted October 25, 2005 Report Share Posted October 25, 2005 How noticiable is the gain with better wires? Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted October 25, 2005 Report Share Posted October 25, 2005 just put my msd wires on 2 weeks ago. Have not noticed any gains in HP or MPG. Didn't expect any HP but i thought they might be worth a little better mileage. I put the heat shields back on. Brad Link to comment Share on other sites More sharing options...
