Apexi Power Induction

[SKLgodzilla]

Hey guys, just one quick noobie question, when i replace my stock R34 air box wit an Apexi pod, there was this black straw like tube connected to the top half of the air box sorta like a black rubber tube (very thin, about 70mm thin). Does any one know what it is or where should i put it? Cos the there is no other holes on the pod to stick this....lol

And another thing, will the new pod drasticlly affect the amound of air that is being inducted into the engine?

Thanks for the help..

Cheers

That tube is a vacuum line. I've been told by people that have done this that it's not important and to tuck it away... though I'm really not certain as to what the particular function of that vacuum line is.

More than anything, a pod will make a difference to the induction sound.

Whilst the pod filter looks good, sounds good and can take in a lot of air quite freely; it will also soak up all the engine bay heat a lot more than an airbox with a panel filter, unless of course you enclose it and run a CAI (Cold Air Intake). A CAI could just be a tube running cold air from say the front bar into the air box

To be honest, you'll be better off just replacing the panel filter with say a K&N High Flow filter as you've got a cold air feed from the opening under the bonnet that feeds into the box, and an N/A can only take in so much air anyways... as opposed to forced induction where the filter becomes even more of a restriction. The first step in unlocking N/A power is relieving all the restrictions in the air flow in and out of the engine, and as far as a filter goes, the K&N Panel will do the job just fine.

I've read about some people's experience with pod filters creating more power in the top end in freeway driving, this is mainly due to the ram effect of the cold air hitting the filter, but that's really the only way that you'll get the most out of a pod filter vs the panel filter.

thanks for the very informative reply, u seem to kno the little details to the Skyline...

just another thing regarding the heat issue, do u think it ll damage the engine if it is left like dat? im plannin on gettin a carbon fibre heat shield if this is goin to cause too much drama....

No worries

If you get a pod like I said just shield it or you'll end up with worse performance for your day to day driving.

An N/A isn't going to see anywhere near the temperatures of a turbocharged Skyline, and a lot of those run unshielded. Colder air = more power; hot air = heatsoak and loss of power as the air intake is taking in cold air. Making up an air box with a cold air feed into it is the best way to get performance with a pod filter.
