Bosch 85001 Spark Plug

Bosch EVO Spark Plug 85001

Bosch EVO spark plug 85001 is built for modern turbocharged gasoline direct injection engines that place higher demands on ignition components. It combines an iridium center electrode, iridium-platinum ground tip, and a projected ceramic insulator to support stable ignition under severe combustion conditions.

• Iridium center electrode with fine-wire design for consistent spark performance.
• Iridium-platinum ground electrode tip for durable wear resistance.
• High dielectric strength construction helps resist irregular combustion events.
• Resistor design and 6000 resistance rating for controlled electrical performance.
• 14 mm thread diameter, flat seat, and 26.5 reach for confirmed application matching.

Fitment and application details

Compatible With 2015-2017 Lexus NX200t, N/A; 2016-2017 Lexus GS200t, N/A; 2016-2017 Lexus IS200t, N/A; 2016-2017 Lexus RC200t, N/A; 2018-2019 Lexus GS300, N/A; 2018-2021 Lexus NX300, N/A; 2018-2025 Lexus IS300, N/A; and 2018-2025 Lexus RC300, N/A. This Bosch EVO spark plug 85001 is also referenced by the same application family under cross-reference numbers 172286 and 182286.

The EVO product line is engineered and produced to the same quality level associated with original equipment spark plugs. That makes it a practical choice for drivers seeking a direct replacement spark plug for Lexus turbocharged gasoline applications where ignition stability and long service life matter.

What this spark plug helps address

• Misfires caused by worn or heat-stressed spark plugs.
• Hard starting from weak ignition output.
• Rough idle linked to inconsistent spark delivery.
• Combustion instability in turbocharged direct-injection engines.
• Reduced ignition efficiency from electrode wear over time.

Installation notes and quality

Verify thread diameter, reach, seat type, and heat range before installation. Use the confirmed vehicle application data for Lexus IS300, RC300, and related models to match the correct spark plug specification. Bosch develops the EVO line to original-equipment standards and to withstand demanding engine conditions throughout its service life.
