## Questions & Answers

**Q: what is inside diameter**
A: Too small to get a 8mm 90* boot through.  About 13/16.

**Q: Will it fit a ls1**
A: I don't think these will fit a LS1. The typical LS1 plug wire is too wide and will not fit into these sleeves. Stock LS1 heat sleeves are metal and the plug wire boot slides into them.

**Q: Do these fit the 10.5 mm spark plug wires?**
A: Regardless of the ignition wire size being used, all plug boots or caps are standard. Use caution mixing solid core wires without resistor type spark plugs. Resistor wires and plugs help peak coil voltage levels at the gap or electrode.

**Q: Will they shield a wire that is touching the header? Or must it be pulled off the header? My number 5 and 7 are tight to the header.**
A: I have used these touching headers, but I also wrapped the headers with heat wrap  https://www.amazon.com/ARTR-Titanium-Exhaust-Stainless-Locking/dp/B012C5FOLK/ref=sr_1_3?ie=UTF8&qid=1533638978&sr=8-3&keywords=header+heat+wrap
This combo kept the spark plug boots from burning on a basically stock Chevy 5.3L
