🔌 Bosch Automotive 7424 OE Double Platinum Spark Plug - Single - Fine Wire Design Review

I've been using them for a while now and the (my wife's) car is running better than before. I don't know how long they will last, but I'm very happy with them. The old Benz (2010 C300) is very demanding and yet there is no jerking or tripping. (I installed them myself). I saved a lot of money!

Installed on my 2009 Benz E350 when I received an error code on the cylinder indicating the spark plug or ignition coil was faulty. Note. My owner's manual lists a plug without a resistor, but the old one was a plug with a resistor, so I installed the same one. The engine runs great, no problems.

This is an upgrade on my original Bosch spark plugs which have lasted 75,000 miles and which I change regularly. Better than OEM connectors for a fraction of the price my local dealers charge. I think they last longer than a car.

Great buy at a great price. If your car needs new ones, which it probably does as they need to be changed regularly, but most of the time it doesn't, then this is a much better deal than the dealer or your mechanic can offer you. Just buy a few and give them what they need while saving a ton of money.

Exactly as in the description. Made in Germany, as stated. arrival on time. Given that German engineered spark plugs are known for their durability and value for money, I believe they will be great for the mileage advertised and expected for their build.

I bought these spark plugs to replace the factory spark plugs in my Benz. After driving almost 70,000, my car hesitated a bit before starting. After installing these spark plugs, my car started faster (without hesitation) and more consistently. My S550 purrs like a kitten. Mercedes uses BOSCH or NGK spark plugs as OE, but why pay double just to have a small Mercedes Tri-Star badge on the spark plug. It's the same part! Highly recommended!

The design and material of these forks are of the highest quality. They didn't need to be corrected. Thanks to the engineers at Mercedes-Benz, changing the spark plugs on the SLK350 is quick and takes less than 30 minutes. After the positive experience with them in my Pontiac, I have already bought Bosch spark plugs for the second time. Not scientifically, but the Pontiac motor seemed to sound smoother, like a purr, after switching to Bosch. So it was obvious to drive with them for the SLK. I…

They fit my 2010 e350 3.5L V6 perfectly for some reason! Some motors are designed to very specific tolerances and I've found the hard way that my e350 motor is one of them. I originally bought Denso iridium candles, trading long life for potentially better fuel burn, and all that put a hole in my wallet. After installing the Denso spark plugs, I had noticeable misfires that shook the engine so badly you could feel it on the steering wheel. I've tried everything; Torque testing, reel boot…

These spark plugs fit my 2012 Mercedes-Benz GL450 perfectly. It struck me that these are basically the same parts that Mercedes sells from its dealerships, minus the star logo and the obvious theft markup. They are otherwise identical and should take into account that Bosch manufactures an original part. You will need 8 of these spark plugs, and to install them you will need a 3/8" spark plug socket with a 5/8" drive, a T30 torx bit, a 3/8" ratchet and if you don't have one already have a…
