Bosch › Ignition coil

I have them with APR Stage 1. R8 coil packs are not really an upgrade that people make them out to be... red = more performance.... Sure they came out of a R8 and V8 Touareg "BAR" engine code... but the coils make enough current to get a spark. The spark plug does the rest, and the features of the spark plug help with getting the air-fuel mixture ignited and burned. Because of the popularity of the red coils, you can often get them cheaper. I think last time I paid about $100 for the Bosch red coils from ShopDap.com

Pros: sufficient current for spark, often cheaper

Cons: not a performance upgrade

Vehicle: Volkswagen Tiguan

I decided to order the OEM Bosch coil off of FCP Euro. Same issue about a 1/4inch too long. Being kind of annoyed and noticing that they're pretty much identical decided to pull the rubber boot off the old and swap it with the new one.

The car now runs a lot better, however, I think the slight difference in ignition coils is making the car run slightly choppy at high rpms

Pros: car runs a lot better

Cons: choppy at high rpms

The Delphi coils are junk. Bosch updated the coils they offered and we've used the updated coil multiple times and never had to warranty a single one out in the 4 years we've been installing them.

Everytime we've used a Delphi in the past the white silicone on the boot degrades and falls apart in 6-12 months and customer cars came back with misfires again.

The old Bosch coils wear out because people don't do spark plugs and replacements on time. The old plugs end up with crazy gaps and it kills the coils. Usually at 100k-120k miles but honestly that's the normal lifespan of a pencil style coil regardless.

If you're plugs are old and you're beginning to experience misfires then save yourself the time do all 6 plugs and coils. Your N52 will thank you.

Pros: reliable, long lasting

Cons: silicone degrades, short lifespan

Mileage: 120000 km

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.

Pros: car feels more powerful

Cons: one coil rusted

Vehicle: MINI

Mileage: 105000 km

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.

Pros: genuine Bosch recommended

Cons: avoid Chinese parts

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.

Pros: good quality, reliable brand

Cons: bad coils out of box

Many aftermarket coils are completely out of spec and do not work well, some can even destroy the ECU. OE, Bosch, Temic are all good, I believe Beru is an OE manufacturer as well.

Pros: OE, Bosch, Temic are good

Cons: aftermarket coils out of spec
