Summary: Performance without parasites
The PVL 401255 cap is specifically designed for the extreme conditions of the competition. It ensures a perfect connection between the high voltage wire and the bougie, while protecting embedded electronics (chronos, sensors) with its integrated resistance.
-
Specific compatibility: It is one of the few caps perfectly adapted to fine-headed candles (threaded terminal) like the NGK R7282 and the DENSO IAE01.
-
Electrical protection: His resistance of 5 kΩ (5 kilo-ohms) eliminates electromagnetic interference that can disrupt your ignition system or telemetry tools.

- Mounting tutorial: maximum sealing
-
Cable preparation: Make sure the core of your ignition cable (Ø6mm) is clear. If the cable is old, cross-cutting 5mm to find fresh copper.
-
Screwing: The PVL cap screws directly on the cable. Turn to feel firm resistance to ensure contact between the internal tip and cable core.
-
Candle connection: This cap clips on the terminal thread of the bougie (without the olive). Push up to "Click" to ensure that the motor vibrations will not cause micro-cuts.
-
Sealing: Check that the rubber seals at each end are well positioned to prevent moisture or fuel projections from entering.
💡 Michel's trick
"In KZ or racing motorcycle, the vibrations are huge. The trick: The bougie NGK R7282 is a bougie Very short and fragile at the level of its terminal. My Pro Council: Only use this original PVL cap. Standard flexible rubber caps end up taking play and create electric bows that destroy the bougie. With PVL 401255, maintaining is rigid and secure, which avoids missing a start because of a cap that jumps! "
❓ FAQ SEO (Frequently Asked Questions)
Q: Why does my description mention "blue" while the reference 401255 is black?
A: Historically, PVL produced blue and black versions. The current reference 401255 is usually Black. The technical characteristics (5kΩ, Ø6mm) remain identical regardless of the color.
Q: Does this cap work with standard candles (with olive)?
A: No. This model is designed for competitive candles without the terminal nut (olive). If you try to ride it on a bougie Standard, you risk breaking the internal clip.
Q: What is the life of this cap?
A: In competition, the internal resistance can end up oxidizing or varying. Measure it periodically with a multimeter. If the value moves too far from the 5 kΩ, change it.
