Magnets will lose their effect over time due to the field weakening over time due to extreme heat exposure depending on where you install them.

On the flip side, I use magnets on my transmission pan, engine oil pan and engine oil filter to trap magnetic particles. Rare earth magnets from dead hard drives of old computers work great!

Whatever works!
