HKS state that engine power is directly related to the amount of air an engine can take in and expel. Therefore, one of the easiest and least expensive ways to increase the horsepower of any engine is to improve the airflow into the cylinders
thats only true if what you have is restrictive, it makes no difference if your filter can flow twice as much as the OEM if the OEM is flowing more than the engine requires, The OEM filter is a good one look at the two base plates the rubber one is a very well known brand cotton filter look at the transition compared to the smooth flowing version on the right thats an oem one
The only problem with the OEM is it sucks warm air in, do like AJs-s2k suggests and you have as good if not better than a lot of aftermarket systems
my suggestion for top set up on NA
smooth wall samco induction pipe
stripped out oem air box with resonator chamber removed
snorkel
3" cold air feed to box
i know its not to everyones taste but i honestly believe this would stack up against most aftermarket systems
Not exactly expecting much more power, but looking for more efficiency, smoother and crisper throttle response and something to compliment my Mugen exhaust and stainless exhaust manifold.
Brian helped me fit my spoon replica snorkel which should do the job. (Although my bonnet latch is fcked so havent been able to close the bonnet to test it).
But a snorkel, new filter and a modified airbox (partition ripped out) should give you a crisper throttle and prevent heat soak.
Once I get the car sorted I'll take you for a test drive if you want.
Have an AEM V2 on mine, it sits fairly low down behind the front bumper so is well away from the engine in case of heat soak. Very happy with it and love the noise.
Is the spoon filter better than the K&N? I dont have the spoon air duct but think its a good copy of it, gets plenty of air.
Does the throttle body make much difference? I think i may start cutting the box then.
