@TonkatrainHONKHONK well, believe it or not, there is still something to be gained from reducing the remaining chunk of noise... :)

@nikushim666 And if the embeded capacitors in the alternator and ECU is enough to charge, why running the car without battery is detrimental? That shows that the battery is still being relied on to hold to voltage and get rid of some spikes right? Only thing, the battery itself has a high internal impedance so it doesn't absorb high frequency noise.
I wanted to stop selling this because of controversies, but due to popular demand I'm resuming.

@nikushim666 a full bridge rectifier with its capacitor doesn't completely remove the noise. It is not just the alternator but the various loads in the car that drain current in a ripple fashion. This overlapping of noise from various source creates its own harmonics as well. So adding a low internal impedance (low ESR) caps in parallel to the line voltage isn't such a bad idea.

@nikushim666 a 4-banger at 3000rpm will have a discharge rate of 100Hz. That means the primary windings of the ignition coil will drain a spike of current once every one hundredth of a second, creating some noise in the line voltage.
So I don't see why this doesn't have an effect. Not to mention that sparks fire at 30,000 volts, and a 0.3 volt drop during that every one hundredth of a second, will lead to 800 volt drop at the secondary winding.

@nikushim666 Nevertheless they are marginal in their noise filtering ability. The whole point of this device is to create a larger capacitance, with minimal internal impedance, and high frequency response so it can adsorb even high frequency/short time interval spike type of electrical noise.

@AndrewChan84 Does the noise even matter in a car? I don't see how that would cause an impact on performance and any electronic device for use in a car should have the ability to deal with noise from the start.

EE wise a capacitor is almost always used in conjunction with a FBR IC package. Every alternator i have remanned contained one. The switch PS circuits on the ECU and ICU systems also contain noise reduction in them one from or another (primary to reduce noise created by ignition coil). Only time i can see them not having them is if it was remanned using substanrd aftermarket parts or just cheaply made with a inadaqute uF rating or low tolerence(precision) parts.

The rect it self does not remove the noise, hense "Full bridge rectifer circuit", keywords there is circuit (not intigrated circuit) Inside a alternator the circuit consists of a rectifier a capacitor/inductor and overdraw failsafe (commonly zener diodes). The capacitor and inductor are what remedy the noise. Besides the point noise will have no impact on the ignition system anyways (considering it operates off a 30+khz disruptive discharge coil).

@125varma Batteries and capacitors have different impedance profile. While battery is capable of churning a hundreds amps when put to a high load, is has very bad frequency response to incoming noise. The battery does not absorb high frequency voltage ripples, and the ripples end up getting absorb by the other components. Low ESR caps have exxellent frequency response.
This is not a power storage device, its a noise filtering device.
mega raizin ftw

@SuperR31 mega raizin cost 3 times and this has similar performance. :)
