Airbox 172

[xoldog400]

The 2 air feeds from ph1 airbox are in very bad condition, so i took them off.
Can i have the airbox without them?

Yeh be fine just a little nosier

 

[xoldog400]

ok, so i can just leave it that way (without these 2 pipes) forever?

 

[domjolly]

yeah no problems at all i have left mine off for ages gets a bit of extreanoise and hot air dragged in is minimal in that part fo the bay

 

[hipwell]

ive never seen a ph1 or ph2 using ph1 box with the pipes there anyway

 

[xoldog400]

ok, thanks! but for example when you wash the car/hood with the miniwash is there a posibillity that water could get to those two holes?

 

[ABOO]

Don't worry about washing car mate, how do you thin people with open cone filters go on???

 

[xoldog400]

ok thanks guys! i will then leave it as it is (without 2 pipes)

 

[xoldog400]

Tested it today (without the 2 air pipes) and...i don't know it don't think there is any difference, maybe a little more noise.
I'm concerned that the box (without the pipes) is going to suck some hot air (esp. in summer) or will it not?

 

[hipwell]

Just leave it mate, where the box is aiming is the coolest part of the engine bay anyway. That's why nobody who runs the JMS setup has a cold air feed

 

[yeecup]

itg maxogen has no cold air feed either.

when you're so worried , get some 73 mm CAF off of Ebay or the like and point them towards the headlight. My experience is, after 10+ trials/experiments with c.a.f. setups, that this works out best on the F4R engine.

Foglight/bumper/forced air induct etc. do not work better, even worse and the filter element gets dirty VERY quickly this way also

 

[xoldog400]

ok, will get the CAF, now what would be the excact diameter (franx said 73 mm) and most important WHAT LENGHT should these CAFs be?
thanks
