K&N Air Filter
Discussion
Don't know about K&N, but I've got a Pipercross cone filter fitted on my 4.0 Chimaera, when I first fitted it I thought it felt a bit quicker, but it was probably phyological.
Looks better than the standard filter especially if its a new shape front end, mines the old spec but it still looks better through the stainless grill on mine.
And you don't need to replace them every 6000/12000 miles just give it a clean and a bit of filter oil and your away, the Pipercross filter was only a few £ more than the standard TVR filter so if your keeping the car a bit there's a cost savingas well as more power (maybe).

The standard filter is a foam type. These tend to be only average in terms of filtration - more dust will get in your engine.
The K&N (if oiled properly) performs well for filtration but won't give any power advantage over a foam filter as they are both low restriction already.
All you could do is improve some of the bends in the system (the one after the MAF is very tight), shorten the pipe length a bit and add a bellmouth at teh filter to smooth the flow. This will give a tiny (probably unnoticeable) improvement.
The power gains K&N show in ads are comparing a normal car intake which consists of tubes, aircleaner box and paper filter. These are more restrictive but do provide cold clean air. Most K&N conversions are sat in the engine bay so they pick up hot air and the restriction benefits are lost.
It is important for power to draw cold air - this s why the filter is at the front in the nosecone on TVRs. However I think it is too low and could suck in water, even in a shallow flood. If you are changing it, move it higher up in the nosecone.

Does anyone have one of these on their Chimaera?
What sort of performance gains are involved? (If any!)
Any down sides to fitting one?
It will do absolutely nothing as the standard filter is pretty well transparent. Been there, played around and saved money.
The down side is that fitting another filter technically makes the car modified and you have to notify your insurers and you can't sprint the car in the standard production class.
