For fear of digging up an old thread, I'll start a new one.

I've seen some people's bodge jobs of a DIY induction kit, and my respect for the nations intelligence seems to be somewhat reduced. Anyway.

I am tempted by a GSR, however, my question is that why could I not make my own?

Flexible Hose

Cone Air Filter

Will this be any less effective than a GSR (providing it is down by a cold air source?) I'm not going to necessarily buy these exact parts, it is just for example. Theoretically, I can't see any difference.


Thoughts? :devil:

You would get a rougher air flow though the induction hose shown above than a smooth pipe but otherwise, little to no noticeable difference I would have thought(y)
 
Seriously? You mock other peoples DIY suggestions and come to us with this?

Solid silicon is used mostly to reduce heatsoak, that stuff you've linked is so thin it'd warm up the air waaay too much, you'd probably end up being better off with the K&N on the tb.
The only thing that kind of tubing is good for is taking cold air to the filter, not for taking filtered air to the throttle body, it passes too close to the engine.

Edit: Thanks Madman0, the rougher airflow thing too ;)

Didn't think about that. So, the criteria is:

Thick silicone
Smooth inside (not corrugated)
Cold air
As few bends as possible

Correct?
 
Aye pretty much. I don't claim to be an expert by any stretch of the imagination but check out my MM thread to see my DIY. It started life as a focus kit but wouldn't fit onto my tb. All in I think it cost about £80.

Edit: Found it to save you searching

My DIY attempt didn't go far, i was going to use the airbox and filer as standard but have heat insulated pipes feed cold air into the box, the idea was to have "forced" induction at motorway speeds...

Never got round to buying the second airbox to try this out, ebay bids for one are over £15:(
 
Flexible Silicone Hose

Suppose I get this (or similar). Route it down to get some cold air and stick a cone filter on the end, how will it do?

Cheers

Go onto ebay and you will find alloy and silicone tubes (straight and curved).

For heat conduction silicone is better but the air coming in wont be standing around for long enough to gain much heat. Its not like its going under the exhaust manifold.

@m20b25 looks neat though could be a larger diameter (the 1746 HGT uses 65mm) and avoid deep water at all costs. But its got cold air and minimal dust which matter 99.9% of the time.

Another issue is avoiding it drumming on the car's body panels.

BTW a half decent system is going to be more than £25 - two silicone bends cost more than that.

ive got a ford focuz induction kit (most popular) but.... ive cut it shorter as the closer u have the filter to the TB the louder/deeper the sound then i got an old henry vacume pipe pushed it into the filter end then connect a (air scoop) no to sure what its called ... to the right hand side vent on the bumper where the air travells in while driving

u can just about see it in the picture

and tbh ino some ppl will disagree with what im saying and will say it wont work but imo i have noticed a difference
the car is more responsive and alot louder than is used to be all in all gears

Thanks

mines louder too,but thats not always a good thing, I cant wait to put it back to standard, it sounds pants and robbed low down power.

To OP, defo do the job properly if your going to bother, a previous owner on my punto has bodged on a cheapo BMC cone filter and a skanky blue hose. it sounds naff and does sod all for performance, after all the necessary jobs its going back to standard.

this is my 1st induction (diy) using the original inlet pipe and a cheap cone filter
DSC00241.JPG
then got a toyo sports induction with heat shield to replace that to reduce turbulance. not a bad kit (16v version of the "focus" kit) for the price.

obviously its not in the ideal place for induction, but it does the trick for noise and a little more response at the throttle. if u want the induction purely for performance, u are better off paying out for a gsr kit. a lot of research has gone into them to get proven gains with variable pipe dimensions etc to give the best flow of cold air. much better than any diy kit.
