How to install spark plug wire heat shields 350 vortex drivers#
The #7 plug at the rear on the drivers side. The purpose is to provide as much room as possible for the hardest plug of all. (Wiggle it and pull, and it should pop out.)Īlso remove the rubber tube from the "black thing" which is attached to the exhaust manifold (see picture). Pull the large vacuum line out of the brake booster and place it out of the way. Remove the Plastic Fuel Rail Covers by gently prying them up. Start on drivers side since it will be the most difficult. Taking a Spark Plug out when the engine is hot can result is valve warpage, or other internal warpage, due to cool air entering a hot combustion chamber. Wicking Grade 290 is recommended for electrical contacts, and is made to seep into tight threads and assembled components. I opted to put a small drop of Loctite 290 Wicking Grade, on Just a moderate squeeze of the pliers, and a moderate twist to ensure they are not loose. Make sure these are snug with a pair of pliers. 057 so I stayed with that.Īlso the NGK's have tips that can unscrew on the top where the plug wire attaches. 060.Īnyway, I checked all the NGK plug gaps, and all were the same at. This was great to me, as I understand anything between. 050 but when I used a knife type feeler gauge, they were more closer to. The NGK Plugs come pre-gapped from the factory, supposedly at. They actually use the Stock Delco boot, and end, to connect to the coil packs. I had just a little concern about their fit though from looking at photos of their wires for the LS1.įit, Finish, and Looks, are very nice with the Taylors. They claim 200 windings per inch, and don't use "resistive enhancing" coatings which can breakĭown in other wires.

If I were to upgrade I would look at Magnecor. This to me seems more than sufficient for the LS1, since the wires are ONLY about 6 Was told they use approximately 80 windings per inch on the Spiro-Pros. I was able to speak to a rep at Taylor Vertex, and I Taylor wires come highly recommended from many hard core LS1 owners who race and modify their engine. I chose to go with Taylor Spiro-Pro 8mm Wires. The LS1 uses 8 individual coil packs to deliver spark to each plug. Notice the much larger copper core on the NGK. Then the TR6 is a better plug, because of its colder heat range.Ĭonsult with your tuner for best gapping etc.īelow is a photo of the NGK TR55(left) plug next to a Platinum stocker(right). If you run your engine hard in a very hot climate, and/or are running nitrous or forced induction. The quenching effect is minimized, resulting in more effective, complete combustion."
The V-Power plug is designed to draw spark to the edge of the electrode. "The amount of spark which is absorbed by the center and ground electrode is referred to as the quenching effect. Increased ignitability allows the engine to burn air/fuel ratios that would otherwise be too lean." This allows easier and more complete combustion of the air/fuel mixture. "NGK's unique V-Power design directs the spark to the edge of the electrode where it can develop more rapidly. Here is NGK's explanation of the V-groove: This is because the center electrode is cut into a V shape. NGK TR55's and VX's are called V-Power plugs. The trade off is that the larger solidĬopper core will dissipate heat quicker than the Platinums, and will deliver a more reliable, more powerful spark. I estimate when driving hard, that replacement will need to come about 15K to 30K miles. The solid copper TR55's won't last near as long, but will The platinum actually won't last that long, and will break and/or burn off if you drive your LS1 hard. The NGK TR55VX plugs are the same plug, but are the platinum tipped version. These plugs match the heat range of the stock plugs and are cross-referenceable to the stockers.
I chose to go with NGK TR55 Solid Copper Core plugs. The part number is S9721 and it costs about $40.00. Tools Requiredīasic tools will do, but I also chose to go with the SNAP-ON Double Swivel 5/8 6-point Spark Plug Socket. It also comes with about 7mm, carbon resistor based, plug wires.
