Product Details
Denso U-Groove Conventional spark plugs are designed around a ground electrode shape that opens the spark path for more reliable ignition in the correct engine setup. The Denso 3070 uses a nickel-tipped ground electrode with a copper-core center electrode, combining durable materials with consistent electrical performance. With a manufacturer heat range of 20 and a standard single-ground configuration, this plug is built for applications that call for OE-style dimensions and resistor ignition characteristics.
This part cross-references DENSO Auto Parts W20FPR-U for the same application. If you are comparing Denso 3070 against other ignition service parts for Honda Civic or Toyota Corolla maintenance, verify thread diameter, reach, seat type, and pre-gap before installation.
Common Issues This Part Can Address
- Hard starting caused by worn spark plug electrodes
- Rough idle from inconsistent spark delivery
- Misfire conditions related to aged ignition components
- Reduced fuel efficiency from incomplete combustion
- Weak throttle response from degraded plug performance
Installation Notes
Confirm vehicle-specific fitment before installation, including thread diameter, reach, seat type, and heat range. The Denso 3070 is a 14.00 mm, flat-seat spark plug with a 12.70 mm reach and 0.7 pre-gap size, so it should only be installed in engines specified for those dimensions. Use the correct 20.6 mm hex socket and follow the manufacturer’s torque and gap specifications for the application.
For Honda Civic, Toyota Corolla, and other import engine service jobs, match the plug to the ignition system requirements and inspect the coil, wires, and related secondary ignition components at the same time.
Quality Assurance
Denso is known for OE-level ignition component engineering, and the U-Groove Conventional line is built to support consistent spark performance in specified applications. Part number 3070 is manufactured to the listed electrical and dimensional specifications for accurate replacement selection.
