I just installed an Alta intake (with silicon hose)

I love the increased blower whine and intake noise! However, I notice an air-hissing/whistle that occures at about 1/3 throttle and drops off a few hundred RPMs later. IS THIS NORMAL? I double checked the fitment of the hose to the throttle body and it seems to be sealed. I just want to make sure this sound isn't being caused by an inpropper seal of the hose.

Thanks

100% normal

enjoy the alta

minigolf · Oct 16th, 2005, 11:46 AM

Yep, normal.

It kinda bugs me a bit on the highway as it flutters on and off at around 110km/h in 6th. But otherwsie, the ALTA is perfect. Can't imagine the car without it now.

Ah, I get exactly the same with my K&N Typhoon, and like you I checked all connections. Nice to know it's normal!

Oldspeed · Oct 16th, 2005, 06:38 PM

Cool, Thanks guys, just wanted to make sure it was normal

St00ge · Oct 17th, 2005, 10:37 AM

100% sure it's normal, i've heard this a hundred times on different threads, i think its just the throttle body or something like that...

XTREEM · Oct 17th, 2005, 02:28 PM

I cant handle the noise of my Alta/Uni filter hybrid anymore.. Its driving me crazy and ruining the driving experience for this "35 y/o old fart".. I am going to order a new smaller uni filter element and put the rear wall back in to hopefully quieten it down a bit.

minigolf · Oct 18th, 2005, 12:23 AM

Can we see some before and after photos too please John.

XTREEM · Oct 23rd, 2005, 01:39 PM

Yeah I can do that Liam but its just going to be a shoter filter. The current one is 160mm lomg where as the new one will be 90mm long.

Before i spend the money I would like to hear peoples experiences with running the Alta with the wall in and out!!! Is the sound alot quieter in the cabin with the wall in?

i don't think the alta fits with the wall in?

XTREEM · Oct 23rd, 2005, 02:04 PM

Yeah it does, they just reccomend it to be removed.

pretty sure it does anyway.

St00ge · Oct 24th, 2005, 09:28 AM

is the wall permanently removed? or can you take it out and return it whenever you want?

Elie

XTREEM · Oct 24th, 2005, 10:12 AM

Elie, It can be put back in but you need to remove the filter and heatshield etc to do it. its not a 5 minute job!!!!

yeh i no, just wondering if they cut anything....

XTREEM · Oct 24th, 2005, 11:04 AM

Nothing cut.

minigolf · Oct 24th, 2005, 12:38 PM

Although they do suggest cutting the rubber strip above the rear wall. I chose to leave the strip stock for now.

XTREEM · Oct 24th, 2005, 12:43 PM

Yeah I done the same Liam. You getting tired of the intake noise yet?

I think i'll cut mine....cold air comes in from below the windscreen....every little bit helps

XTREEM · Oct 25th, 2005, 11:35 PM

Liam is talking about the rubber not the wall, leaving the rubber in place isnt going to block any air, just gives you the option of putting the wall back in when you get sick of all the noise and not having your rubber cut up.
