Granatelli GM LS & LT 0-Ohm 8" Red High-Temp Spark Plug Wires – 28-1811HTR
Couldn't load pickup availability
No extra length. No unnecessary resistance. Just a compact 8-inch connection engineered to get your ignition coil's available energy straight to the spark plug.
```The Granatelli 28-1811HTR 0-Ohm High-Performance Spark Plug Wire Set is designed for performance applications where space is tight and clean coil-to-plug routing matters. Its compact 8-inch boot-to-boot length helps eliminate excess wire while maintaining the strong spark delivery Granatelli 0-Ohm wires are known for.
Built with 8mm red high-temperature silicone insulation and a spiral-wound stainless-steel core, these wires combine high-temperature durability, EMI/RFI suppression and maximum available ignition-energy transfer in a compact package.
```8 INCHES BETWEEN YOUR COIL AND SERIOUS SPARK.
```GUARANTEED 5–10 HP GAIN
Naturally aspirated applications can see a measurable horsepower increase, while supercharged, turbocharged and nitrous combinations may see even greater gains.
```Key Features

- OE-style fit and finish
- Pre-assembled and ready to install
- Complete V8 set – 8 wires
- Made in the USA
Built for Tight Installations: At only 8 inches from boot end to boot end, these wires are ideal when the ignition coils are positioned close to the spark plugs. Less unnecessary wire means tighter routing, less clutter and a cleaner, more purpose-built engine bay.
Maximum Spark in a Compact Package
```Your ignition coil can only do its job if the energy it produces reaches the spark plug. Granatelli's 0-Ohm conductor design is engineered to minimize resistance through the wire so the maximum available coil output reaches the plug. That makes strong, consistent ignition especially important in high-RPM, high-cylinder-pressure and boosted combinations.
```Designed for High-Heat Engine Bays
```Performance headers, turbo manifolds and other exhaust components can expose ignition wires to serious under-hood heat. The 8mm red high-temperature silicone insulation is rated beyond 500°F and designed to withstand demanding street, strip and race environments.
```Compatible GM LS & LT Applications
```Designed for compatible GM LS and LT coil-near-plug applications using the correct 8-inch boot-end-to-boot-end wire configuration. Always verify physical wire length and ignition layout before ordering.
Common Engine Sizes
```| Engine Size | Common Applications |

| 6.0L | LS2, LQ4, LQ9 and other compatible LS applications |
| 6.2L | Compatible LS/LT applications using the correct wire configuration |
| 7.0L | LS7 |
Important Fitment Notice: These wires measure 8 inches from boot end to boot end. Engine family or displacement alone does not guarantee physical fitment. Compare your existing wire length, ignition coil location, spark plug boot configuration and routing before ordering.
```Heat Notice: The high-temperature silicone construction provides increased protection in demanding engine bays, but proper clearance from headers and other extremely hot exhaust components is still recommended whenever possible.
