Product Details

The Denso U-Groove Conventional line focuses on OE-style spark plug construction for vehicles that require a specific ground electrode profile. Part number 3195 uses a multi-electrode ground configuration with nickel materials at the firing surfaces and a copper-core center electrode, supporting reliable spark delivery in the applications listed below. This part cross-references DENSO Auto Parts (e.g., K20TR11) for the same application. It is a direct-fit option for select Toyota Camry, Toyota Avalon, Toyota Sienna, Toyota RAV4, Lexus ES300, Toyota Solara, and Porsche 911 applications that specify this plug design.

What This Spark Plug Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent ignition at the cylinder
• Misfire conditions related to degraded plug electrodes
• Reduced throttle response from weak spark delivery
• Service replacement for vehicles calling for the specified U-Groove Conventional design
