BOSCH 9621 OE Fine Wire Double Iridium Spark Plug - Advanced Original Equipment Technology with 4X Life - Pack of 4

Near OEM performance at 25% of the cost! Bosch Quality replaced NGKs/Toyota OEMs. Great value and now the engine is running smoothly! I have seen a slight improvement in my mpg @1mpg overall in mixed driving conditions.

Had one cylinder misfiring so replaced coil and spark plug. Runs fine now, but old plug looked shot after only 5 months so I think the coil was the problem. Really good plug so far but very expensive.

The best quality. Runs like new again.

After seeing a quite ludicrous $403 quote to change 4 spark plugs in a Mazda3 I decided to show my son how easy it is. These were an upgrade from OEM parts. They were gapped perfectly for the car. They took 20mins to fit and work fine.

They’re made in Germany, what else can you say

Definitely better than the old plugs that probably had 80k miles on them. The one star off is because I had a misfire after installing. Not sure if I damaged the plug or what, but a reinstall didn't fix the misfire. In my genius, I rushed to try to gap it and ended up breaking the iridium tip. Put the old plug into cylinder 3 (where the misfire was) and it was fine. Gonna have to get a new single tomorrow at my local shop, but a bit frustrating to get a misfire after install.

Everyone has their favorites. These were one of three that were recommended for my vehicle. They do not need anti seize on threads. They are pre gapped. Easy install. I checked about anti seize lubricant. Special threads, anti seize not recommended. I checked gap. They all measured to spec. Quality product . Hope this helps and May God Bless !

This is NOT a good fit for the Nissan/Infiniti VK50VE!!! Amazon lists this as being an OEM part, but it is not. OEM is from NGK. The VK50VE is a very finicky engine and putting anything other than true OEM in it is likely to cause issues. The gap is off, too. Look up the NGK part number on a cross reference chart to get the right plugs. It is not worth the risk you're taking to buy these.

Seem great so far. Installed in a 2016 Mazda 3, 2.5L engine. Noticeably improved low-end torque, like the engine was when it was new. Will report back if I run into any issues.

This is a great buy. From Amazon warehouse. Difference between new and used is this. Customers return products that dont fit. They are open box. So if u buy one of these that actually fit your car you can get 50 percent off!
