Have to agree Paul, my XKR is twice the age and displaying nowhere near the levels of corrosion in the engine bay,

I contacted Lexus dealer and this is what they said about the corrosion. 

“The aluminium in the engine bay is not treated at manufacture due to the hot conditions it is subject to with everyday use. This is why you see the oxidisation – perfectly normal and nothing to worry about”

Not convinced 🤔

How about anodising the part?

Purple anodised parts were very popular in the MTB community ...😉

If you clean off the oxidation and paint on a protective coating, this will need to been maintained on a regular basis, particularly in the hostile enviroment under the bonnet.

Hmm, sounds like a plan 🤔 Thanks for the suggestion. 👍

Don't Lexus anodise the intake manifolds on their F cars? That's a very cool looking purple/blue.

As long as the part doesn't sustain physical damage i.e. scratches, the protective anodising should last indefinitely.
