Ignition coil Bosch or NGK

When I bought my 2008 VW Rabbit 2.5, it had 142K miles on it and I wanted to be sure I did a complete tune-up, not knowing its history. I bought the whole OEM unit which came with cover, gasket, bolts and PCV valve at a low price from Amazon. When I pulled the coils to replace the plugs, I saw that they were covered in oil from the leaking center section of the gasket, so I bought NGK coils to go with the NGK iridium plugs. When I pulled the plugs, I saw the tops were also covered in oil but the working end of the plugs were fine (Bosch plugs and the original coils). Replacing everything was easy and I torqued everything correctly. No more leaks and the car performs wonderfully on 87 octane.

Had thrown some 2 years ago and still running clean as ever

I pulled all the coils out and one of them was rusted to shit. As I mentioned, I didn't want to pay $460 to get them from MINI, so the parts store supplied me with Bosch coils and they worked well. I ripped the car through the business district I work in ala Grand Tour; all the stuttering problems, hiccups are gone and the car feels way more powerful than before.

Be sure to use a genuine Bosch from a reputable source, or OE from the dealer. DO NOT use a Chinese one from a big-box auto parts store.

Make sure the new coil is a good Bosch, Beru, or OE unit, not parts-store brand junk. I've seen plenty of bad coils out of the box.

I ended up getting a brand new Bosch ignition coil from German Autoparts for around $160 shipped with a few other small parts. This was around November last year.

Go Bosch, or Go Badly.

Performance gains from only a coil, I don't know, probably none, however the car I have it in is completely stock in the engine department. As an addition to mods I think the coil is a good idea because it helps to smooth out these cases when mixture is out of stoich Maybe better throttle response.

Worthless cause it doesn't have an internal pin.
