  • Great OEM replacement.
The search engine failed me on this one. A 2001 Cadillac SLS is a V8 engine. Without looking I ordered this 6 pack because it said it fit, technically 6 does fit into 8. I will just order 2 more. The plugs themselves are OEM, gapped, dependable and durable. Will increase my fuel economy, performance and run smoother. They were a great purchase. I just need to pay closer attention to the search results better. ... show more
