Verification rule: check the model suffix and year/serial label, then confirm LKR6E / 09482-00649 in the Suzuki maintenance chart. Do not assume it fits an earlier DF150/DF175/DF200 solely from horsepower.
Quantity note: the listed engines are four-cylinder models and normally require four plugs for a complete change; this listing supplies one plug.

Frequently Asked Questions
How many plugs are supplied?
One genuine Suzuki-supplied NGK LKR6E spark plug.
What gap should be used?
Suzuki application data specifies 0.8–0.9mm. Check and set the gap to the service manual for the exact engine.
Does it fit every DF150–DF200?
No. It applies to the listed A/AP generations; older model families can specify a different plug.
What tightening torque should I use?
Use the torque stated in the Suzuki service manual for the exact engine and installation condition; do not rely on a generic torque value.
Note: Install on a cool engine with clean threads. Start the plug by hand to prevent cross-threading and follow the Suzuki service torque.
