Throttle Bodies and plug covers

Me again...

Was looking at some nice Caterham spark plug cover for my K series after my cover got lost when the hgf was fixed. Found some really nice covers that come in red gold or silver, not decided what colour i'm having yet.

But as i was shopping, also found some aluminium throttle bodies for the K series, to replace the OE plastic one.

Anyone reckon these would be worth purchasing and fitting? Trying to squeeze every last HP out of my girl so the wider bore may put a bit more HP out... or maybe not.

What do you guys reckon?

Go for the silver cover, they make you go faster than the red covers

Cheers N.I.

The Caterham lettering looks nicer and more readable on the silver one, still not decided though. I've seen an Elise S1 plug cover on ebay as well, but the Caterham ones look like they're at least made out of metal and better made.

I can tell everyone i've got a fast engine with one of these in! haha
