Piaggio 080341 High Voltage Spark Plug Cable Ø 7 mm – Vespa, Ape, Aprilia, Gilera, Guzzi

The Piaggio A.T. base cable 080341 is the original high-tension cable from the Piaggio Group: it is the conductor that carries the impulse from the ignition coil to the spark plug. With an outer diameter of 7 mm and black insulation, it is the standard replacement part used by the manufacturer on hundreds of models, from 1978 to current production: Vespa, Piaggio, Ape, Aprilia, Gilera, Moto Guzzi, Derbi, and Scarabeo. A deteriorated spark plug cable is one of the most frequent — and least suspected — causes of difficult cold starting, loss of rpm uphill, backfiring on deceleration, and unexplained increases in fuel consumption: the insulator ages, high voltage finds a path to ground, and only a weak spark reaches the plug. Replacing it is a quick job that restores the engine's full ignition, just like when it was new.

✓ Strengths

• Original Piaggio spare part — manufacturer code 080341, official name «CAVO BASE A.T.» (Base High Tension Cable)
• Extensive coverage — the same code is specified by the manufacturer for Vespa, Piaggio, Ape, Aprilia, Gilera, Moto Guzzi, Derbi, and Scarabeo
• 7 mm diameter, the standard size for Piaggio Group ignition systems
• Intact insulation — no high voltage leakage to ground
• Immediate installation — can be replaced with only a spark plug wrench, without engine disassembly
• Negligible cost compared to benefits — it is the spare part with the best cost-benefit ratio for ignition performance

Recommended products

The cable works with the rest of the ignition chain: if you are changing it, it's the right time to also check the spark plug, spark plug cap, and high-tension coil. In our catalog, you will find original Piaggio spare parts for each of these components, so you can renew the entire system in one go.

Who it's perfect for

• Workshops and mechanics who daily work on scooters and Piaggio Group vehicles and want to always have a spare cable in stock
• Those restoring a vintage Vespa or Ape and looking for the original manufacturer's code, not a generic equivalent
• Those with an ignition problem — difficult cold starting, power delivery gaps, backfiring on deceleration — and want to rule out the cheapest cause before addressing other issues
• Those performing preventive maintenance and replacing the cable along with the spark plug during scheduled services

Frequently Asked Questions

What is the Piaggio 080341 cable?
It is the original Piaggio high-tension cable, cataloged as «cavo base A.T.» (base high-tension cable). It has an outer diameter of 7 mm and is black. It serves to transfer the electrical impulse from the ignition coil to the spark plug and is the spare part specified by the manufacturer for most of the Piaggio Group range.

Which vehicles is the 080341 cable mounted on?
The official Piaggio catalog specifies it for Vespa, Piaggio, Ape, Aprilia, Gilera, Moto Guzzi, Derbi, Scarabeo, and Laverda, from historical models of the 1970s to the most recent productions. This includes Vespa GTS and Primavera, Piaggio Beverly, Liberty and MP3, Ape 50 and Poker, Aprilia SR, and Moto Guzzi V7.

Is it an original spare part or an equivalent?
It is the original Piaggio spare part, identified by manufacturer code 080341. It is not an aftermarket with a cross-reference: it is the same component mounted in production and distributed by the official network, with the designation «CAVO BASE A.T.» listed in the manufacturer's catalog.

Is the spark plug cap also needed?
It depends on the condition of your current one. Code 080341 only includes the cable: the spark plug cap has a separate Piaggio code. If the installed one is intact, flexible, and shows no cracks or signs of discharge, it can be reused without problems by screwing it onto the new cable.

When should the spark plug cable be replaced?
When the insulation is hardened, cracked, oily, or shows signs of discharge, and whenever difficult cold starts, power loss under load, or backfiring on deceleration occur. Many mechanics replace it preventively along with the spark plug, given its minimal cost.
