  • intake modifications

    I've run out of intake mods that i can do practically.. I put on some 3.4 intakes, the 56 tb, and topped it off with a cone filter right off the MAF. In late fall/winter/ into early spring that set-up is good because really cool air is always getting into the engine bay.
    The problem comes in the summer months, when it's 14 billion degrees under the hood and 90 degrees outside with humidity (southern Ontario, Canada). The cone filter at that time right off the MAF is retarded. I switched back to my stock air box and of course there is a difference. This got me to wondering... and i came up with these findings.

    I took apart the intake, removed the MAF and took it apart. Using cleaner, I gently cleaned each MAF wire to it's original finish. I grinded down the fins running through the center to knife edges at each end. I matched the diameters as well as possible and put it back together.
    I took out the MAF screen, I know what it does, but my stock filter works at the micron level, so im not afriad. It makes sence that removing the screen improves flow.

    I removed the headlight and removed half of the intake plumbing. The top half that it attached to was then pointing right at the fog-light hole... so I removed that fog-light.
    The last thing was run some ducting from behind the grill pointing toward the valley between the engine and airbox. The extra ventilation is probably good while moving.

    After all this, I decided to put the cone back on. Now anything after 10 kilometers an hour will force wind through all the modified/added plumbing and provide at the least a cooler charge.
    That, plus the removal of the MAF screen have yeilded some noticeable results... We've had a couple low-humidity/cool nights where I really feel the pull.
    Intake mods are the most common, so I thought I'd share my story here.

    P.S. I'm not worried about the bare MAF and after market shit cone filter. I know it's not good, but anything good isn't good for ya.

    The screen is to even out the air so that it reads correctly. Oiled filters too close to the MAF can contaminate the MAF if it's over oiled.

    Put a K&N drop in the stock box, and work on modding that to breathe more. It takes a LONG time on the highway to cool down the temps with a cone. and it still doesn't get as cold as the box or a real CAI.

      Buy an AEM Synthetic filter so you don't have to worry about oil on the MAF.

      You can also build an air box around the cone filter to isolate it from the heat.

        Yeah... MAF + K&N oil don't match. Made a bit of cash from people over oiling them and the car would no longer run .

            wow... thats just pretty. Yeah thats a nice way to build it. The Malibu has a battery in that area, and the available duct hole isn't round.

            I like the way the stock box breaths for my application. It's just 3400 intakes on it... so I actually feel like the cone filter is redundant, in that like Isacc says, it takes too long to get cool air to it. whatever I've done so far, it's worked well.

            I'll say this though, my transmission isn't going to hold up. Not from power, just because it's a piece of shit light duty one.

              ATM I use a drop in K&N, and I cut basically half of the bottom portion of my airbox off. That stupid snorkel that went behind the headlight looked too small to me... So from mounting tab to mounting tab got cut off with a saws-all. I still left the lip that the filter sits in intact so that the box makes a good seal around it so filtered air goes in my engine and not junk. I have had people comment on how good my car sounds when I get on it, and they ask what kind of exhaust I have on it (especially after going through underpasses while on it) and I have to tell them, its 2 1/4 mandrel bent with stock mufflers on it, your hearing the intake. Having that thing gutted lets a lot more sound out, and it sounds a bit meaner.

                that maf screen straightens out the the air so the maf wires get an accurate reading based on speed and temp of the air. turbulant air is slower, and thus doesnt 'cool' the wire the same.

                u gotta question why gm would spend money to put a screen there if it wasnt needed. we know that the general is a cheap bastard.... think about it

                      Hey keep your head up and don't be a stranger! I'd like to see an ITB 60degreeV6. The electronic valvetrain sounds expensive though! LOL With that no need for a throttle body though if you use it that way!

                          Yeah, Cat has been using camless engines for a couple years now, and lexus keeps talking about it, supposed to have a camless engine out now, but I dunno. Toyota put out lots of rumours though...

                          A camless engine would be amazing though...

                              Lol. Fair enough. Guess all the money I drop at the Uni to get GM specific training is worthless . But my associates and bachelors will also be like the ASE certs. Just paper.
