« Bosch Spark Plugs - Best on the market ! »

I purchased Bosch spark plugs for both of our cars. After the intsallation the cars both had improved engine performance. When I took the spark plugs out of the box I saw the excellent quality amd workmanship that went into them. I would recommend this product to anyone thinking of tuning up their car or is in need of spark plugs. I also just installed Bosch wiper blades and they perform excellent and are well worth the higher price.

« Perfect Plugs in my Impreza »

These have been running strong now for 30,000 miles. They start the car 1-crank faster and have not given me any trouble. Fuel economy is what it should be as well.

I will purchase these again when they are worn. Finally, a good spark plug from Bosch!

« Good Plug - However, No Noticeable Fuel Mileage Increase »

I have two Toyota Camrys. A 2004 SE and 2006 LE. Both have the same 4 cylinder engine. I have always been religious about checking the gas mileage on my cars at every fill up because this relays to me if anything has gone awry. The '04 had 115,000 miles and the '06 had 45,000 when I replaced the plugs. I replaced them mainly to see if it would help the fuel mileage; unfortunately for me, no difference. I'm sure they are good plugs as Bosch is well known for their high quality, however next time I will probably replace using the factory spark plugs.
