I would appreciate some advice please,
looking to squeeze a few extra bhp out of our fsi.
looked at a remap but think that is expensive for 7bhp
seen k&n filter for <£50 which seems quite good, also seen a Jetex induction kit which claims better performance improvements for similar cash but not familiar with IK's and whether they deliver, how easy they are to fit, insurance implications etc.
Anybody any experience ?
Cheers
 
Re. insurance, strictly speaking, ALL mods should be disclosed to the insurers and then it's up to them to decide whether to load your premium or not!

Keep watching this space, as I think a refined remap will soon be on the cards for the FSi at Stealth. As to induction v. filter, I think both will give similar results, but as most induction kits also include a new filter element, that would probably have the edge. You really need something that takes the air mass sensor into account too though.

Cheers,

Hi Tony
Many induction kits draw warm air from under the bonnet outweighs any slight improvement in airflow you may get. If the kit does not include a system to duct cold air to the filter then its not worth bothering with.
With a standard engine, a clean paper airfilter element should provide all the air flow the engine needs. The advantage of a K&N is that it can be cleaned regularly which gives a long term cost saving and if your very lucky you might get a slight increase in performance but probably not enough to notice.
I'd go along with Mike's advice and wait for a refined remap from Stealth - and use 98 RON fuel.

I've seen that product before and I've got to say, it looks ok-ish, but I can't see that it would be much of a benefit, possibly a hinderance as that fan (25,000 rpm - in your dreams, looks like it's been robbed out of a computer case) could well reduce airflow by retricting the intake cross-scetional area.

See what Vince can rustle up first and save your hard-earned.

Cheers,

Mike
