Look, basically a "freeflow" air filter will slightly improve the breathing
of the engine. Indeed many respected tuning houses will recommend fitting
one of these but in conjuction with other mods, like a sports exhaust
manifold and system, a hotter cam and a different fuel set up.
You might get, what, an extra 1bhp from your engine? The long pipe induction
kit is usually used as underbonnet bling, and because it's metal it
resonates differently under acceleration. So you get more noise.
It's usually more beneficial to make your own long ducting (from salvaged
intake trunking at the scrapyard) to a so-called cone filter somewhere in
cold fast airflow - like to the side and in front of the radiator by an open
intake in whatever body mouling your car has got. It costs very little.
These things attach with little more than jubilee clips. If you're orifice
diameters don't match up simply sleeve with more or less trunking. It's only
air that you're guiding not an fuel/air mixture. As long as the unions are
reasonably secure, and you're working upstream of things like airflow meters
etc then you'll be fine with DIY.
