Frequently Asked Questions
What engines does the Autolite 4194 spark plug fit?
Answer: The Autolite 4194 is a 10mm thread, 12.7mm reach, flat seat plug commonly used in many small engines, including lawn mowers, generators, pressure washers, and other outdoor power equipment. Always check your equipment manual or existing plug for confirmation.
What’s the difference between Autolite 4194 and NGK CR5HSB?
Answer: They are cross-compatible equivalents. The Autolite 4194 matches the NGK CR5HSB (6535) in thread size, reach, heat range, and seat type. Either will work in applications calling for these specifications.
Do I need to gap these plugs before installation?
Answer: Yes. While plugs are pre-gapped from the factory, we recommend checking and adjusting the gap to 0.025″ (0.635mm) using a wire-style gap tool. Never use a flat feeler gauge on a worn electrode.
Are these genuine Autolite or aftermarket?
Answer: These are 100% Genuine Autolite spark plugs, manufactured to Autolite’s exacting quality standards—not aftermarket copies.
