BoschOxygen Sensor - 17276

Used on my 987.1 and fit perfect. Better than OEM. Treads come with anti-seeze of some sort. Easy installation and have not given me a CEL.

Perfectly fits the Porsche 997 Turbo upstream. It's slightly longer than the stock one, which makes it easier to connect. There's another one, Bosch 17307 which also fits, but more expensive...beats me as to why.

Exact OEM Porsche Boxster part. Price was hundreds less then a stealership purchase. Fit perfectly but wiring was tricky as it's sports car engine.

OEM oxygen sensor for the Porsche. I pulled the original plugs out and they were identical. Check engine light is now clear.

Looked and fit just like OEM for my 2006 Porsche Boxster. German made. Happy with it. Came pre-lubed with anti-seize compound.
