On the casual glances I've had at the air-filter area (yes, its behind the RHS headlight) I reckon it'd be fairly easy to fabricate an enclosure to force it to draw air only from outside the engine bay- effectively building a CAI

I'd envisaged controlling the engine temp by increasing insulation in the engine bay, e.g.

Thicker Insulation on the bonnet/hood

An under tray below the car to seal off the compartment

Upper/Lower grill blocks

I believe my car may have an EGR- I may have a raid at the weekend and clean/clear whatever I can in the engine bay- can't do much harm!

Some googling, and conversations with mates suggest that the Bosch fuelpump on our lumps is happy with veg.

Key seems to be starting off with low concentrations (10/20/30%) and slowly ramp it up. Additionally fuel filter changes to catch any crud flushed out would be a plan. Filters are cheap..

Once I get past 30% veg, I'd see a significant decrease in fuel costs per mile..

I like the upper grill block/belly pan combo.

Rear wheel skirts and Kamm back would attract (unwanted) attention.

I could, however, possibly go for wheel covers, and possibly "spats" to deflect air round the tyres?
