On this cylinder head is mounted a short base spark plug therefore B9HS for example.
To the delight of all enthusiasts, many of you asked us for it, so we did it. Here is the RRD cylinder head Ø46mm high compression diameter with decompressor for Peugeot 103 engine equipped with a 70cc kit in diameter 46mm.

Our cylinder head preserves a chamber like the original cap. It also preserves an original aesthetic appearance. It is a 40mm base cylinder head, fully digitally resurfaced for perfect planning, controlled, and with a chamber specifically increased to 46mm with a calculated angle.

It will offer maximum performance to your high 46mm diameter motor and mate to it perfectly! The aesthetic appearance does not differ from other known radial models and out of production. It is an original base cylinder head and radial type with large fins to optimize air cooling, cast in polygonal molds.

We recommend it with SP98, the price may seem high, it is however low in view of the work carried out on these cylinder heads digitally in small series with complex and ultra precise adjustment, but mainly its unique marketing on the market for Peugeot 103! During the planning, increase of the compression and recovery of the angle, of the diameter of the chamber, we also had the RRD logo digitally affixed.
