Less Pipework V8S Air Intake - Low Cost

You want air that's as cool as possible going into the induction system - cooler air is denser = more power. You've changed to the air intake sitting fairly close to the exhaust manifold from drawing air at the front of the car. I agree the original arrangement is a bit convoluted but that's why they did it. Look under the bonnet of any car and it never has the air intake under the bonnet - it's always piped to the front or through a wing.
I've done this mod on mine, and as far as I can tell, it's made absolutely no difference to the way it runs.
The air around the filter might well be hotter than ambient when the car is stationary but once on the move the air flow under the wheel arch is at ambient.
Before I did this mod, I took temperature readings at the AFM and compared them to ambient. At rest, with the standard pipework, the air reaching was (IIRC) 4 or 5 degrees above ambient. So even the standard design was inefficient.

It was a conscious decision Barky C - Hot at standstill yes but not at pace. No, at pace the lower pressure from the wheel arch area will suck air away from the filter 
The principle of the cold air vs. hot air thing is true, but the reality is it makes little to no difference. I've dyno tested lots of cars, and on a couple of occasions on some of my owns cars, I've run some with cone filters, some with OE filters, some with no filters, blower fan on, blower fan off - all the combinations I could think of that could affect temperature. No difference in power output - exactly the same. And that was with a modern V6. With something like a Cologne or 4.0 RV8 (and I mean this with no disrespect) they couldn't suck the leaves off the ground in standard tune, so bad is the airflow through the inlet system and the heads. So in reality, I don't think it'd matter where you put the filter.
Personally I'd have kept it at the front and fitted some decent alloy solid ducting etc, if it were me. But it's not
