Read the reviews but still ordered, sold by and fulfilled by amazon so I knew if anything went wrong I would be ok. Got the correct size and they were the made in china variety. Installed in a 2013 Corolla S and the length was either the same or a little shorter of the part with the igniter than what I pulled out. Install went fine, car ran fine, just a little bit more responsive than before, pretty much the same. Idle was better. Gas mileage improvement? Cant notice any. Been a little over two weeks since put in, everything still fine. If anything fails will update review. 7 year satisfaction, probably will have another car before that, but good to have. Was hoping to have gotten the made in germany ones, but that didn’t happen. Still happy with the product.
Update June 2020
Car has been and still is running like a champ. No problems at all with these plugs.

Easy to install. Worked perfectly and still going strong 10,000 miles later.

Received counterfeit Bosch spark plugs, did’nt have the following on the box, check for a Bosch Secure Code Label with a hologram that glimmers in rainbow colors under direct light and verify the 18-digit code on Bosch’s authentication platform.

Exactly what I needed. Arrived on time in perfect condition.

Great spark plugs and do a well job easy to put in however one thing that would make everyone’s life easier is for it to come with the little rubber ring to put inside the sockets to pick up the old spark plugs as not many people have something like that and if you’re doing it yourself like me, need to have that rubber piece to take out the old plugs or will spend 20 mins finding something you can fashion into something that could grab the plugs in a job that should have been 10 mins with my type of car

Took about 2 hours for the replacement process, but it was easier than expected overall. Wiper assembly was the biggest pain to remove. If you have a car that’s easier to operate on, you’ll have no issues with doing this.
The sparky bois themselves seem to be great. Engine runs MUCH smoother both at idle and under load, and I have a noticeable gain in power over my (very) old spark plugs that were previously installed. The most noticeable difference in MPG is on the freeway which went from over 50MPG to almost 60MPG average at 65MPH cruise controlled. Because the engine is (almost) always on on the freeway, this is how I know it’s due to these new sparks.
