DIY Intake Question...
Is it possible to do this on our SC 430?

I think it will work better then having a Injen or Weapon R intake...

If you plan on running a filter like that you'll need a proper head shield, the heat shield in that pic is crap. The idea is to block all the hot air from the engine bay, if you can block all the hot air and introduce fresh cold air from the outside to the filter element then you will be good.
I would suggest you go over the the sc300/400 section and research a mod called "BFI intake", in my opinion it works very well and that's what I have on my SC

Hi Edmond
I have the Injen and it is great. Makes a fabulous sound and when you remove the air scoop for the original intake it leaves a gap where plenty of cold air is driven into the engine bay when on the move. Can't say I have noticed any improvement in performance, but neither any problem with hot air.
Don't know the technical reasons why heat would be a problem, but would have thought the amount of cold air entering when on the move would counteract the heat.
Maybe someone could chime in and give the tech reasons about the heat.
Best regards
Steve

Most likely has to do with density.
1 liter of hot air will have less molecules per unit volume than the same volume with cooler air. Similar to inter cooler on turbos. At least that's what I remember from physics. However I don't think the difference is that much at daily stop and go. Best benefit would be at highway velocity.

So do you think that at motorway speeds the amount of cold air entering the engine compartment though the gap between the hood and the radiator left when the original air scoop is removed would cool the air entering the Injen so that it makes little difference?
Maybe it would be possible to make a new or adapt the existing scoop to direct air directly to the filter???
Anyone have any views on this?

Hence the term cold air intake. If we are talking about normal rides, do not think it will make a huge impact on gain on hp. The pleasure comes from the sound...right? At least for me it is the thing that makes me smile.

Maybe I should just leave the intake alone...
The problem with the Injen intake is the metal pipe, heat gets in it... dyno score is lower than stock intake, but it sounds nice...

As far as I am aware the Injen will fit all models, Some do not require both hoses to be connected and you just blank one off.
Can't help with price because I had mine shipped from your side of the pond, but it seems about right. I will check who I got mine from and PM you.

How did you make that intake? Was the sound any different? It looks like you took the piece off a gs300 cut it and attached the cone filter?
Im interested in doing this as my budgets pretty low at the moment lol
