Platinum TT Design Details

The Platinum TT line focuses on consistent ignition performance through a twin-tip configuration that helps the spark kernel develop more quickly. The platinum center electrode and titanium enhanced ground strap work together to support cleaner combustion characteristics, while the copper core helps maintain conductivity. Denso 4507 is a practical OE-style spark plug choice for drivers servicing older BMW 750iL and 850Ci models, as well as Mercedes-Benz E320, C280, and Toyota Celica applications.

This part cross-references DENSO Auto Parts PQ16TT and Ford AGSP32P for the same application.

Common Symptoms This Spark Plug May Address

• Rough idle caused by worn or fouled plugs
• Hard starting from weak ignition output
• Misfire conditions tied to degraded spark delivery
• Reduced fuel economy from incomplete combustion
• Loss of throttle response from inconsistent ignition timing

Installation Notes and Tips

Verify thread diameter, reach, seat type, and heat range before installation. This plug uses a flat seat and 16.0 mm hex size, with a manufacturer heat range of 16. Check the gap against the vehicle service specification before installation, even though the pre-gap size is listed at 1.0 mm. For fitment-specific service, confirm the exact engine application on vehicles such as 1994-1995 Mercedes-Benz E320, 1986-1993 Toyota Celica, and 1990-1992 Geo Prizm.
