Hero Genuine Spark Plug for HF Dawn & HF Deluxe | OEM Ignition Plug | 31916KST920AS

Product Description

If your bike has become hard to start, is misfiring, idling rough, losing pickup, or giving poor mileage, the spark plug is one of the first service parts to check. 31916KST920AS is a genuine Hero spark plug, and Hero’s official store currently sells this exact SKU as Spark Plug - HF Dawn.

For customers, this part should be described simply as:

• spark plug
• ignition plug
• engine firing plug
• Hero spark plug

The cleanest official fitment is HF Dawn, while strong seller references widen the supported fitment to HF Deluxe as well. So the safest storefront logic is to lead with HF Dawn and include HF Deluxe as a supported additional application.

This spark plug is usually replaced when:

• the bike becomes difficult to start
• engine firing becomes weak or irregular
• mileage drops
• throttle response feels dull
• routine service replacement is due
