Making a VR6 Suck (Better...)

The Idiot’s Guide To Installing a VR6 Intake.

    The stock airbox is large, nondescript, ugly, and extremely evil. With all the other plastic-covered objects in the engine compartment, the intake could be easily mistaken for the battery, a veritable angel. Before beginning, put on latex gloves, tie back any loose hair, and put on eye and ear protection. Remove small children and animals from the immediate vicinity. Begin. Proceed with caution. Any sudden movements may cause a violent explosion. No horseplay, this is a very delicate procedure.

    Using an abnormally large pair of pliers, loosen the clamp that connects the rubber intake pipe to the M.A.F. sensor housing. Unscrew the bolts on the top of the airbox. Once these bolts are out, the stock air filter can be set free in the wild (1A,1B,1C).

    Disconnect the M.A.F. sensor wire harness from the stock intake piping. The removal of the harness is not necessary, but it sure makes the installation easier. Disconnect the intake pipe from the M.A.F. sensor housing. Disconnect the airbox side of the smog pump.

    Remove the bolts that attach the base of the stock airbox to the car. Don’t lose these bolts, since they will be used to attach the heat shield securely. Calling upon the Herculean strength of your Nordic ancestors, rip the entire intake box from the car. Disconnect the M.A.F. sensor housing from the stock airbox with a freakishly long Phillips head screw- driver and connect it to the heat shield with the supplied bolts and nuts.

    Unclamp the engine side of the smog pump hose and slide the ITG breather filter on. Clamp the breather filter to the pipe coming from the engine, and make sure it doesn’t touch any part of the engine. There is a chance that if there is any contact, Lucifer will again be released to walk the earth.

    Reconnect the stock intake pipe to the M.A.F. sensor housing. Plug the M.A.F. sensor harness back into the M.A.F. sensor housing. Slide the ITG air filter onto the M.A.F. sensor pipe. Tighten the hose clamps using the shortest Phillips head screwdriver available (Made by the Pygmies.—MAX) onto the silicone hose, making sure the filter doesn’t rub on the sides. Remove your perfectly clean gloves, let your hair down, release the kids from the bomb shelter, go to the bathroom, and show off your new intake. If it doesn’t look like the pictures, seek shelter. Preparation time to avoid horrific disaster: 3 hours. Time if you just put the intake in without any unnecessary safety measures: 30 minutes. MAX time (A.K.A. sitting on our butts and watching someone else do it.—MAX): Keg (1 hour.—MAX).

What has to be one of the biggest problems with the Mk 4 GTI VR6 is how the car isolates the driver from the road by having very little auditory feedback from the engine. Sure, the power is great. What other car offers so much power in such a small package? Shifting is hardly ever needed with the VR6, which cranks out 181 lb-ft of torque. On the other hand, the driver must possess Superman-like hearing to discern the 174 horses from wind noise as the little beast pulls you into triple digit speeds. The sound deadening that VW incorporates is great for the average driver, but let’s face it, what average driver is going to spend the money on the VR6 power plant? Instead, most motorists are going to save their money and head for the 2.0L 115hp Golf.

Performance enthusiasts live for the power of the VR6 and the growl that should accompany it. Instead of spending hours on the phone to Germany, feverishly flipping through a German/English dictionary and trying to give a convincing argument for the need of engine snarl, we looked for an aftermarket product that would ease our cravings. The easiest solution to the problem was to increase noise from under the hood through the use of an aftermarket intake. While engine noise initially drew the desire for an intake, we knew we didn’t want to spend money on something that would only create auditory stimulation. After a brief thought session, the ITG Cool-Flo Air Intake with heat shield from Euro Sport Accessories was chosen. The intake allows engine noises to be transmitted out of the engine bay instead of being muffled by the restrictive stock airbox, while the heat shield allows cooler air to enter the engine, producing a denser air charge and, consequently, more power (That’s a good thing.—MAX).

In the end, our dreams were met (Most of them, at least.—MAX). Under acceleration, the engine allows itself to be known. And it doesn’t hurt that the engine is now able to inhale a little easier—the way its overachieving nature requires.
