Ignition timing adjustment connector [Ignition Resistor] for HA23 Alto Van, etc., with direct ignition K6A. Even in NA cars, which are difficult to power up, the engine's rotational feel will change. The image is an example of installation on my car (K6A turbo). This is a set of 8, 9 (high-octane specification), 10 (high-octane specification), and 11 (high-octane specification). I often get asked, "Will it fit on [car name]?" If you open the hood and the relay & fuse box, you will find a black item with numbers written on it. You will replace that with this. Please check first. On my car [genuine replacement air cleaner, catalytic converter straight exhaust, boost 0.9, racing plugs], it works without any problems, and it is unlikely to break if you use high-octane fuel, but there are individual differences and tuning variations, so please install at your own risk. Normally, it is not included, but for the 24 Alto, MH21S turbo, and other models where the resistor is attached to the edge of the case, there have been issues where it cannot be installed due to interference. As a countermeasure, an extension harness shown in the image is included. If you are affected, please contact us immediately after purchase. If we do not hear from you, we may ship without it, so please be aware. We can ship it later, but it will cost an additional 500 yen. We have also prepared the popular 7 (regular gasoline specification) option, so you can choose it. This is the price for 4 pieces, so you can replace any of the others. You can freely combine the 4 pieces, such as four of the same number. Please contact us immediately after winning the auction. If we do not hear from you, we will ship the standard set of 8-11. If you want a set of 5, we will list it separately for 1650 yen, so please contact us via the comments section. * * * No individual sales or price reductions, please.
