Hassle-free maintenance Each spark plug package features a customized QR-code that leads to detailed mounting instructions. Workshop tips Tighten using a torque wrench Mount the spark plug by hand as far as it will go, then precisely tighten using the correct tightening torque as indicated on the package. Replace the whole set at once Replacing spark plugs as a set simplifies maintenance, prevents misfires and ensures engine reliability. It is also a time-saver. Do not lubricate the thread Applying lubricant to the threads can lead to over-tightening. Over-tightening spark plugs can lead to engine damage.

After all that I have just checked on the Bosch website and yes these are correct and will fit your car… ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fabulous spark plugs. *by B***D on 9 December 2025* Replaced my wife's mini plugs with these, and had no issues.
