DIY Cold Air Intake Hose with Super Heavy Duty Industrial 3" PU Hose

[sr18autech]

Bought 3" super heavy duty industrial PU hose from Huakenny (Bought some times ago, but no time to do the CAI, until today). It's so durable and tough, and it cannot bend more than 80degree, so I have to come out with a DIY, thus this morning, did all the process below.

And the result was Superb Engine Response !

The Finished Product

Stuffs - 3" PVC Elbow, 3" PVC Pipe, Drill Saw, 3" Alloy Funnel, 3" & 5" Hose Clip, Pipe Tape & PVC Glue

Bosch Drill Kit

Circular Saw, variable sizes

Choosing the right size of the Circular Saw

Close up of the Circular Saw

Circular Saw mounted on the Bosch

The location of the funnel intended to be placed

Ready to drill

Drilling (Only took less than 10 seconds!)

Done!

The 3" Elbow and the Pipe

The 3" Heavy Duty Industrial Flex Hose

Fitted perfectly

Applying PVC glue

Attaching the elbow to the flex hose, with a 3" hose clip

Elbow in place, fitting the 3" Aloy Funnel

Wrapping the Aloy Funnel with white tape

Fitting the Aloy Funnel to the elbow

Very-very tight fit, need some effort...

A view from inside

Fastened the 3" flex hose to the airbox

Airbox connected to the flex hose

STOCK engine bay, hehe

Be sure, to make the CAI airtight, amazing effects will happen.

PS: They are ppl debating whether it will suck debris or water into the CAI n damages the engine, but HEY, if there's flood or really dusty/sandy area, everyone is SMART enough not to drive over those places.....right ?

Adios :)

Nice nice work ..but but .. why did you drill at the side ??

Nice nice work ..but but .. why did you drill at the side ??

easier to fit, dun ned route to front :p...i gues

 

[loose_end]

So , the wind can come from the side ?

 

[sr18autech]

haha, actually there are a few concerns

- Front bumper, not enough flat spread for the funnel to reside properly
- Facing front, anything could sucked inside including debris, sands, birds, squirrel and etc
- Facing front is obvios fugly
- By using an elbow facing side, during rain it prevents water from sucked into the airbox

by the way, the concept is base on my puny brain, so nothing to shout about. but the effects was better throttle respond during a hot day, especially traffic jam. tapping the pedal and the car moves :)

one hint for u my brother , go visit shops that does industrial air cond , pipes etc etc , it's very very cheap and durable , i bought mine like less than RM19 but no funnel.

 

[dreamsquall]

this time dun put water inside ur airbox wor... CAI intake should give u sufficient cooled air....

 

[huakenny]

funnel i gues Brothers got :)

 

[sr18autech]

Actually if u dont mind, go to hardware shop and buy PVC pipe connector, those 4" to 3" connectors, it's also can be used as a funnel.

How to DIY making it look "automotive" is up to your skills and creativity. No point spend so much buy aftermarket stuffs if it doesnt worth the money.

As long as the hose is 3", it really works well no matter the funnel facing side or forward.

Anyway, if you guys needs a drilling, you can contact me, I can do it FREE for you, but ofcoz in return u belanja me a drink or anything....hahah !

Coz I felt shops givin a drillin n ask u pay RM30-40 is nonsense, the circular saw I bought for RM45 only, and so much size I can drill....haha

water is not an issue unless its a flood
little bit of rain wont hydroclog ur engine, chill guys
we pump water injection into the intake more than droplets of water hehehe

nice 1 bro.. got use... if punch a small hole at the L shape there better. water can drip out.
just my opinion ya

a good idea

 

[mokomoko]

i did my own DIY CAI in less than 20 mins with a washing machine hose.
no drilling no poking holes. Just ziptied

ill upload pictures if anyone wants to see my super not clean and unprofessional work

 

[sr18autech]

thank you jinkl, that is called water injection, i know that setup. depends on individual what they want to out perform with their engine.

momoko, washing machine hose is too small and they flex too easily coz too soft......3" hose will give significant engine response.

thanks, but I think that is not neccesary, unless its a flash flood.if there is, simply pop the hood n disconnect the hose attached to the airbox, kautim
