I check different vendors, all seem to have slightly different numbers for the bosch, which I believe to be the factory replacement.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

What is the consensus for the correct spark plug for a 2003 996? I check different vendors, all seem to have slightly different numbers for the bosch, which I believe to be the factory replacement. I'm looking to order from local NAPA Canada, or from Rock Auto.....other vendors get nailed with high brokerage fees.

POST 2Original post

On my 04 I am using Denso 5304 Iridium TT plugs set at .031 gap. works great.
