Description

We recommend the Torch K7RTI spark plug for most small-block Predator, Wildcat, Tillotson, and other clone engines.


The K7RTI’s optimal heat range and performance make it ideal for a wide variety of gas-powered setups. Its heat range excels at self-cleaning, effectively burning off fuel deposits that often accumulate with richer fuel mixtures—something colder plugs struggle to do. If you experience a slightly rich idle, this plug helps prevent fouling and maintains consistent ignition.


Featuring a fine-wire electrode design, the Torch K7RTI delivers a more concentrated and stable spark. This is crucial as cylinder pressures rise and fuel mixtures are tuned richer for maximum power. Higher pressures and richer mixtures tend to extinguish the spark, leading to misfires and power loss. Our testing shows more consistent air-fuel ratios on O2 sensors, indicating improved combustion efficiency with this plug.


Dyno results can vary depending on calibration, test procedures, and engine setup, but we’ve observed horsepower gains of approximately 0.2 to 0.3 hp without altering the engine’s compression ratio or tuning.


Due to the generally weaker ignition systems in these engines, we recommend setting the spark plug gap between 0.028" and 0.032" for optimal performance.

FAQ

Q1: Which engines are the Torch K7RTI spark plugs recommended for?

A: We recommend the Torch K7RTI for most small-block Predator, Wildcat, Tillotson, and other clone engines. It’s designed to perform well across a variety of gas-powered setups.

Q2: What makes the Torch K7RTI spark plug ideal for these engines?

A: The K7RTI has an optimal heat range that excels at self-cleaning by burning off fuel deposits commonly caused by richer fuel mixtures. This helps prevent fouling, especially during slightly rich idling conditions, and ensures consistent ignition.

Q3: What is special about the fine-wire electrode design?

A: The fine-wire electrode creates a more concentrated and stable spark, which is essential when cylinder pressures rise, and fuel mixtures are richer for more power. This design reduces the chance of spark extinguishing, misfires, and power loss.

Q4: Will I see a performance improvement using the Torch K7RTI?

A: Yes. Our dyno testing shows horsepower gains of approximately 0.2 to 0.3 hp without changing engine compression or tuning, thanks to improved combustion efficiency and more consistent air-fuel ratios.

Q5: What spark plug gap should I use with the Torch K7RTI?

A: We recommend setting the spark plug gap between 0.028" and 0.032" for optimal performance, especially since these engines often have weaker ignition systems.

Q6: Does the Torch K7RTI help with fuel fouling issues?

A: Absolutely. Its heat range and self-cleaning ability help prevent fouling caused by richer fuel mixtures, maintaining reliable spark and ignition stability.
