【AS Uotani】SPII Plug Cord 1m Review

Ignition System Refresh

I was having trouble starting the car in the winter.

Standard Plug BP5HA to NGK Iridium Plug

Ignition coil for MC47 (Standard Tune in MC22)
OEM Parts still available for purchase.

Plug cord for the Uotani SP 2 (Plug cap is OEM)
Material:Silicon is soft and easy to handle.

Remove the OEMPlug cordassy from the Ignition coil.
Disassemble the Plug cap and Plug cord.
Cut the UotaniPlug cord to the length of the OEMPlug cord.
If it is MC22, 1m will be enough.
Assemble the plug cord and attach it to the Ignition coil.


Caution!
The NC47Ignition coil is plugged in #2 and #1.
Since it is shallower than MC22Ignition coil,
It will be a little longer to match the OEM Length,
Adjust the length.

Uotani SP2 + UltraSilicon plug cord is ideal.
It is expensive anyway, so I think it can be implemented with a low budget and be effective.

Startup is better and Idling is more stable.
The 6-speed 40 km/h is also easier to ride.
Torque did not experience any thickening.

I think it depends on the individual Engine and Carburetor.

It is effective enough. View detail

Very ordinary Plug Cable

It is a simple cable with the same twisted wire type as NGKRacing cable. Therefore, the resistance value is almost zero, which may be a disadvantage in terms of noise. Even if the resistance value is almost zero, the current flows only a few mA, so there is almost no difference in voltage against tens of thousands of volts. So, in the end, I think it is a Cost-oriented Cable, since it is only slightly cheaper than SpiralCarbonCoat's MSDCable.
Cable is a better looking, more elaborate and more affordable product that is reminiscent of high performance. View detail

I need a PAMS style plug cord for 1PCoil.

The 1PIgnition coil from PAMS could not be used with the plug cord connector provided by PAMS. I did not know this.

This meant that we had to purchase a new plug cable with a 7mm external diameter and crimp the terminals. Crimping the terminals requires tools that most people don't have, so most end users and motorcycle shops will probably just use a pliers to do the job.
It would be a shame to reduce the reliability of the product in order to leave the installation work to the user. Absolutely, it is better to prepare a method that can be used in the same way as for 2P by the MANUFACTURER.

I have recently come to think that even AS Uotani, which I feel is very reliable when I drive a Z, etc., is not entirely reliable when I look at how it is set up for different car models and detailed Spec. View detail

2nd old car to Replace.

I was a little concerned about the quality of the standard secondary high voltage cord for HCraft's IGCoil, so I replaced it.
The flexible and easy-to-handle screw is also easy to screw into the coil side and cap side, and the screw bites firmly, which gives a good impression.
I felt that it was a good thing that AS Uotani, TopBrand's TopBrand in the ignition system, had adopted it. View detail
