My coils were not defected just that the engine was a little rough. I bought this to replace mine. Easy to install: pushed hard all the way down to make sure that they sit on the right position. Then reset the computer. Hard to for me to explain why: at the first 1-2 days I didn't feel big improvement of the performance but I did feel a little better runs. start from the 3rd day, the engine ran smoother apparently . Obviously the new ones are better than the replaced ones, for that I also cannot explain why better. Not happy that 2 boxes of the 6 are opened boxes. I would think that they were returned items by somebody else. Who is happen to get opened box for what he/she purchased?

well built, original Bosch coils, made in Slovenia. Fit and work great in my BMW E90 2009. the original coils lasted 150,000 km and started misfiring in cylinder 2. ordered a set of 6. the first package they sent had the wrong item number, but exchanged for a second set that was perfect. easy install, took about 30 minutes to remove all the beauty plastic covers to get to the engine itself. easy do it yourself job. no issues with electrical socket plugging in. excellent purchase

It was a pre-owned item, discounted accordingly but I took a chance. I'm on a budget and didn't want to spend OEM or OE new prices, and this item was selling for less than aftermarket prices with a OE name Bosch. I nor the seller know if this will work with my car, a pre-LCI 2006 BMW 330i E90. I really just needed one or two of the plugs as I was getting a misfire on one cylinder. I wasn't sure if it was the ignition coil going bad or if it was just a loose connection with the coil plug. I figured it's just better to replace it all since I just got the car and slowly doing preventive maintenance (ie replacing all the brittle aging plastic parts in and around the engine), so this wouldn't be out of line knowing the mileage of the car and the history. The package came, I inspected it, looks new to me, like probably the same situation I was thinking-somebody bought it, opened it to install and it wasn't the right coils for their car and returned for a refund and the seller had to resell at a discount since it's not new. Well, after like 3 weeks now, I can say, my car runs great. Smooth, no more misfires and check engine lights, I drove hundreds, probably a thousand miles now and not one ignition related issue. Thank you to the seller and Amazon. I saved money and the ordering and delivery time was fantastic.
