NGK plugs are perfect for your Vespa 2 stroke motor. The E plug has the longer threads for P200 cylinder heads and the stock Stella heads as well as the newer 177cc Malossi cylinder heads as well.
**This plug is pre-gapped at 1.1mm which is too large for out Vespa application and needs to be gapped to .8mm. The small end does not unscrew on this plug so the NGK cap is recommended.**
