HKS 43001-AK003 Twin Power Ignition Amplifier II - Mazda RX7 86-96

The HKS Twin Power ignition amplifier incorporates both the CDI and transistor method ignition to provide optimum spark duration and maximum voltage output, resulting in crisper throttle response and a smoother engine powerband. The CDI method, capacity discharge ignition, provides maximum voltage by transferring all stored energy in the capacitor to the ignition coil so that the ignition current can buildup quickly, thus making the Twin Power very effective in the higher revs where a normal spark would tend to diminish. This strong rapid spark prevents the high rpm ignition miss that reduces peak power.

The transistorized method generates high voltage by using transistors to cut off current to the coil, thus allowing for a long energy discharge. This longer spark duration allows the Twin Power to improve lower RPM throttle response and torque. The combination of the CDI and the transistor method incorporates two distinct systems into one high performance unit, hence the designation of Twin Power. Expect a spark output that is typically 1.5-2.5 stronger than that of the stock ignition system! Each compact and attractive Twin power unit is constructed of durable anodized aluminum and sealed to prevent corrosion from moisture. General wiring harnesses are included in each unit to aid in installation and mounting. Vehicle Specific wiring harnesses are also available for certain models to further aid in installations that require intricate integration. This is a perfect upgrade for any Mazda RX7 with a rotary engine. Even with mild modifications an ignition amplifier will give you better throttle response and a stronger spark.

The shelves sag away from the wall overtime
Color: White, Number Of Shelves: 2, Size: 15.7in, Color: White, Number Of Shelves: 2, Size: 15.7in
Although the wood quality and finish of the shelf are clean and well-made, the main issue is that the shelves begin to sag over time while holding around 10 pounds, even though the product listing claims they can support up to 20 pounds. They may perform better on a brick wall, but on drywall you should be cautious. To fix the problem, I had to purchase floating shelf brackets for support, which solved the sagging issue. However, this defeats the purpose of the “floating” aesthetic. Since the shelf is in my bedroom, I can overlook it, but I personally wouldn’t install these in a common area if I wanted a clean floating look.
