    Yes as spares. I have a higher than Normal idle vacuum which sits at 17.5inhg. So after chasing some leaks and making repairs like my throttle body gasket and intake manifold gasket I thought I would try replacing the check valves and I just havenít gotten around to it yet.

    Under load I see 24-22inhg and off throttle at speed I see 22.2 more consistently so i havenít really had the urge to dive in just yet.

    @22 each I didnít get ripped too bad LOL

    Do yall think an HPX MAF will make any noticeable different at partial throttle and idle?

    I haven't heard of any noticeable difference, especially on K04 turbo.
    But maybe there are some on here that have had first hand experience.
    I wouldn't think its worth the $$, but that's just my opinion

    He's on K24's but as far as the question, I will let others chime in.

    Your talking blow through maf right? I've wondered if there would be a gain without running the stock ypipe and doing a blow through maf.

    Pretty sure he just means a hpx. Not blow through.

    Iím simply talking about switching from a Hitachi 85mm to an HPX with zero other changes. Not for more power, but smoother idle and partial throttle

    i personally do not think so no. I run an hpx on 85mm and can say things are less smooth than when I was on hitachi, however, there's many variables that have changed like the motor and turbos during that process. Logically, I do not see how it would make a difference.

    From my experience, injectors above 600CC just do not have as smooth of an idle as smaller ones. When I was on K04's I ran 55lb injectors on e85 and that thing purred like a kitten. Now I am running 1000CC Injector Dynamics, some of the best injectors around, and my idle is sub par. Just the trade off for more power.

    Changing maf sensors isn't going help I don't think. If you had a 102mm housing then went to 85, maybe. If all the hardware is in line, it may just need some tuning since it was tuned before with janky check valves. As far as the injectors go, I don't know why, buy my 1300s on E idles perfectly. On the stock coils it would stumble every once in a while, but on the R8 coils it's baby's ass smooth. I don't have a good explanation for it.

    Even my B8.5 Allroad idles better on E85, even though itís still very smooth on 93. But it feels a touch better on E. Idk why

    Dana is making me this intake. I think it will help a lot since my cone is directly on my MAF housing at the moment lol

    FWIW- Would the addition of a flow straightener help
    ie- something similar to the stock MAF housing...the sensor may "like" a more laminar flow and may respond to air flow changes more better --engineering term :)
    YES-I know it would introduce another pressure drop, across the housing, but it may help...In general one would need 5 to 10 pipe diameters, in length, from the inlet to the sensor, to eliminate the issues cause by the eddys and resultant turbulence produced at high Reynold numbers (ie- LOTS of mass air flow). That, however, is impractical.....

    makes sense. Car actually idles smoother now with the longer intake spaced out from the MAF sensor. I posted a pic of it on the lowercase S4 group and people either liked it or shit on it calling it a hot air intake... they're not wrong but its been tested that having a box doesnt make a shred of difference with regard to power or IAT. Plus I added back the air duct to direct air down to it which while driving should push a bunch of warm air away from it. I'm also using meth so I'm not sure it would matter anyways. I was all excited to take the car for a long rip this weekend but I went underneath because it popped a P1557 ....and took a look around.....pass side wastegate line had a big ass tear in it. Explains so so so much.

    Car was all notchy and partial throttle felt like crap. I went around replacing every single vac hose, T, check valve, N249, N80 and slapped brand new 710Ns on. I feel like a dumbass for not looking underneath earlier.

    I like the CAI or HAI depending on who you talk to.

    I like the look, I like the noise, I like intakes period. Back in my Honda days I did testing for about 8 intakes on a Honda Dyno day to see if the OEM box vs name brand intakes would make a difference. Out of OEM AEM K&N and this Whale Tale $400 carbon piece... the AutoZone special with a dry filter made more power than them all mid range and top. All did make Power from 4-9hp and about 3-6 ft tq.

    Not much, but Gains are gains!

    Anywho Iím sold on mine and think it made some difference. Too bad I cut up my OEM box I might have tested them just to see.

    So I was made a believer in the intake way back when and I still am a believer!

    Anybody know the part number for the Mann oil filters (XL size?) I only see the small ones for our cars coming up on FCP and europa

    Thanks. Theyíre 5.95 on FCP right now. I might grab a few. (mann). I run 5-7 degrees cooler it seems with the larger filter and more oil. Seems worth it

    Glad you're seeing a noticeable difference! I have ran both the OEM size and the "large" 940/25 and saw little to no difference in temps and oil test results. Now on a 1.8T I would ONLY recommend the larger 940/25 as that platform could certainly use the extra oil capacity due to the sludge problems. Just be aware that the 940/25 will rest against some hoses since it is such a tight fit, at least mine did when I ran them. $5.95 is pretty good!
