A Predator 212 is a Honda GX200-pattern 212 cc engine, but it is not a reason to fit a random performance plug. Start with the plug removed from your particular Hemi or non-Hemi engine and match its 14 mm thread, 19 mm reach and projected resistor design. The usual F7TC/BPR6ES family is a useful starting point; heat range and electrode gap must still agree with the engine manual or a builder’s documented tune. These are distinct, readily available replacement plugs and equivalents—not claims of extra horsepower.

The picks, in detail
NGK BPR6ES
The widely used NGK replacement in the F7TC-equivalent family for a stock-style Predator 212 when the removed plug and manual call for this specification.
- 14 mm x 1.25 thread
- 19 mm reach
- Projected resistor electrode
- NGK heat range 6
- Common small-engine replacement
- Easy to source individually
- Confirm gap and heat range for your exact engine
Torch F7TC
The common original-equipment-style marking found on many 212 cc clone engines; use it as the comparison point when matching a replacement, not as proof every Predator revision shipped with it.
- 14 mm x 1.25 thread
- 19 mm reach
- Projected electrode
- Resistor-style small-engine plug
- Directly familiar to many clone-engine owners
- Inexpensive multipacks
- Quality and sourcing vary by seller
Champion RN9YC
A Champion cross-reference option for the BPR6ES/F7TC-style plug family, useful when a local parts counter stocks Champion rather than NGK.
- 14 mm thread
- 3/4-inch (19 mm) reach
- Resistor construction
- Projected center electrode
- Widely stocked service brand
- Straightforward cross-reference choice
- Check the cross-reference against the plug removed from your engine
Autolite 3910
A readily available Autolite equivalent often cataloged for GX200-pattern engines; it is a practical replacement only when its catalog application matches your Predator revision.
- 14 mm thread
- 19 mm reach
- Resistor plug
- Nickel-alloy electrode
- Often available at auto-parts stores
- Low purchase cost
- Do not substitute by thread size alone
Denso W20EPR-U
Denso’s resistor projected-tip alternative in this common small-engine size, for owners who prefer a Denso cross-reference after verifying reach and heat range.
- 14 mm thread
- 19 mm reach
- Projected resistor design
- U-groove ground electrode
- Distinct electrode design
- Established ignition manufacturer
- Availability is less universal than NGK
Bosch WR6DC
A Bosch resistor plug in the same basic 14 mm, 19 mm-reach family; use the catalog number only after matching it to the original plug’s specification.
- 14 mm thread
- 19 mm reach
- Resistor suppression
- Copper-core center electrode
- Common Bosch service-line option
- Good for buyers consolidating parts brands
- Cross-reference tables can differ by application
E3.36
An E3 small-engine plug marketed as a replacement for BPR6ES-style applications; choose it only after confirming the catalog lists your engine’s original plug family.
- 14 mm thread
- 19 mm reach
- Resistor design
- DiamondFire ground electrode
- Alternative electrode geometry
- Sold through many hardware and auto retailers
- Costs more than a conventional nickel plug
NGK BPR5ES
One heat step hotter than BPR6ES in NGK’s numbering, so this is a conditional choice for documented cold-running or fouling cases—not a blanket Predator upgrade.
- 14 mm x 1.25 thread
- 19 mm reach
- Projected resistor electrode
- NGK heat range 5
- Same physical-format family
- Easy to distinguish by NGK number
- A hotter heat range is not suitable without a specific reason
NGK BPR7ES
One heat step colder than BPR6ES, reserved for a documented hotter-running modified setup where the builder specifies it; it is not a stock-engine power part.
- 14 mm x 1.25 thread
- 19 mm reach
- Projected resistor electrode
- NGK heat range 7
- Clear colder-range option within the same family
- Useful when a documented tune calls for it
- Can foul in an engine that does not need a colder plug
Buying tips
- Read the ceramic marking on the plug you remove before ordering; thread diameter alone does not establish correct reach or heat range.
- Set the gap to the value in the manual for your exact Predator revision; do not assume a pre-gapped plug is ready to install.
- Hemi and non-Hemi references usually concern cylinder-head and valve-train differences, not permission to use an arbitrary plug.
