I use Bosch Platinum +4 spark plugs in all of my cars. You can easily and instantly tell a difference in engine performance after installing these spark plugs. The best part is that you get a mail in rebate with each pack that you purchase which makes them cheaper than other subpar brands.

Had my 2001 Mustang for many years before using Bosch Platinum+4Spark Plugs. Changed the plugs and my car went from baaaaaaaaaaa to SHOOOOOOOOOOOSH. Plus got a big fat rebate for doing the modification. Hey Bosch why don't you make Throttle Positioning Sensors. Anything other than from the manufacturer is junk. Maybe a double SWOOOOOOOSH?

I recently installed these plugs in my 2000 ford ranger.  When I took it for a test run I immediately felt the difference in throttle response.  I am very pleased with the increase in power and also the fuel mileage has increased.  I am one that checks fuel mileage every time I fill up.  My ranger has a 3.0 litre engine when I first got it I was getting 18 miles to the gallon.  Well since then I have added a K & N air filter which incresed my mileage to 21.  I then added free flow dual exhaust and to my surprise increased my mileage 1.5 miles more to the gallon.  And now with the bosch platinum + 4 plugs I've noticed 4 more miles to gallon, I couldn't believe it and double checked the mileage and it was right and has been at every fill up since.   So now I'm getting 26 to 27 miles to the gallon.   Wow, that really still impresses me !

The Bosch Platinum Plugs are one of the greatest things to happen to the automotive industry.  Many consumers still think that a spark plug is a spark plug, but they are misinformed.After doing much research and asking around, I decided on the Bosch Platinum plugs for my 1995 Ford F-150.  It was riding a little rough and I had just purchased it from a co-worker so I decided to replace the plugs.  I purchased my Platinum plugs and went to work.  My truck's engine went from riding like an old truck to riding as smooth as a car.  Since the Bosch Platinum Plugs are pre-gapped from the factory, there was no need to gap my plugs.  I was confident that those plugs would give the optimal performance that they give me now.  And since there is no need for adjustment on the plugs, I don't have to worry about future misfires.They worked out so well in my truck that my wife and I put them in her 1996 Toyota Carolla.  When we first got that car it got 28 MPG.  After some new Michelin tires, Mobil 1 synthetic oil, 93 octane gas, and Bosch plugs and wires, it averages 35 MPG.If you treat your vehicles right, they will treat you right.  Keep up with regular maintenance and you will hopefully avoid major car costs in the future.  Bosch Platinum Plugs are a great part of investing in the right parts for your vehicle's engine.
