Induction Kits
Induction kits are, quite simply, an assembly of parts that encourage greater airflow from outside the car to the engine. The vehicles ECU then compensates for the additional air by introducing more fuel, and thus, an increase in power is expected.
For many car modifiers, an induction kit is the first item they will fit to a new car, as they can be bought relatively cheaply and produce a modest power gain. Induction kits also make the car produce a throatier, more sporty sound due to the increased airflow.
Most induction kits can be fitted at home, however if you are unsure, it may be worth employing the services of a local garage. The most important thing is to ensure the kit is fitted properly, otherwise particles could penetrate the engine and cause significant damage.
Popular brands of induction kit include K&N Filters, Pipercross, Powertec, Green Filters and ITG. More specialised induction kits are also available from brands such as HKS, Blitz and AEM, designed for highly tuned cars, usually Japanese performance cars such as the Nissan Skyline, Toyota Supra and Honda Civic Type-R.
The power gain that can be expected depends on the parts bought, and the car you drive. For the best advice, consult your retailer or check out the manufacturers website.
