Spark Plugs for S55 - Controlled Gap Setting

On the S55, ignition problems are often not resolved by fitting new spark plugs, even genuine ones.

This can show up as an unstable idle, misfires, and hesitation or random stalling.

We have the solution: high-quality NGK spark plugs, gapped correctly for the fuel used (SP98 or ethanol).

Price for a pack of 6 NGK spark plugs, gapped and checked.

Team Lupos tip:

"Spark plugs with the right gap give better ignition, but also wear out sooner. Allow for 8 to 10,000 km of use."
