🔥 Enhance Performance with MAS 8.5mm Spark Plug Ignition Wires for Chevy/GMC 1999-2006 LS1 VORTEC 4.8L 5.3L 6.0L Engines Review

After 3 months there was an error. It turned out that one of the wires had about 2 strands of conductors that transferred the electrical charge to the connector.

Excellent cable. LS heat shields fit perfectly. Extra length provided for different uses, can be trimmed and shortened. I will buy again. Very happy with them.

They are too long for a 2002 Chevy Tahoe 4.8L. They are useless to me now for cutting into metal as they are at least 5 inches longer. He said he did, but he didn't. Don't buy this if you have an LS based Chevy.

The boots were too tight on the coils. The wires were at least 2 inches longer and had to be twisted heavily to keep them from touching each other and other underhood parts. They were installed within a few months and there were no performance issues. They look good and are inexpensive.

I'm disappointed with these wires, they didn't last 5 months. I started my truck the other day, it backfired so badly I didn't know if I would make it home. I went to check the candles, 2 wires out of 8 disconnected with little or no voltage. Save money, buy a good brand from the parts store.

They worked fine. They don't look like interchange with my 2010 Tahoe. They are longer but worked well. 2 of them loosened around the block after a short session, they jumped out and missed. adapts quickly and purrs like a kitten. My Tahoe seems to have responded well. So no complaints from me.

These cables look great straight out of the box but that's about the only good thing I can say about them. When fitted they are too long compared to the original and if fitted correctly without touching the header(s) it looks ugly and for those who want a clean engine bay it will ruin everything. Then when I started the truck I had at least 2 dead cylinders, I tried adjusting all the spark plug leads to make sure they were ok but to no avail. Strongly do not recommend spend extra money on high…

But they look cool curled up a little. I have round coils which I think are closer to spark plugs. Put on red spark plug guards so they work with my Kooks heads. Kooks also recommends trimming the flat tabs on the black spark plug boots to get clearance, which was easy and seems to work. Update: This has made the idle stumble worse. Went back to the previous wires and the idle improved greatly. It may have been too long or just an incompatibility with the Chevy engine, but ultimately I have to…
