MK4 JETTA MOD UPGRADE
DownpipeĪgain, one single upgrade isn’t going to turn your MK4 GTI into a different car. If you just want to make one or two upgrades, you’re better off with coilovers and wheels. If you follow everything on the rest of this list, an intake is a must. Our Luft-Technik intake system for your MK4 GTI does add some power out of the box, but the majority of an upgraded intake’s benefits happen when you pair it with other upgrades. Think of it as future-proofing your engine.
However, if you have plans to make your 1.8T into a respectable power source, then you’ll need an upgraded intake. If you’re just looking to spend money, then you could arguably get more bang for your buck making your MK4 GTI perfect rather than just dumping money at a single upgrade. It’s an age-old question and one we’ve previously answered: should I spend money on a cold air intake? The answer, in short, is yes, but there is a caveat.
MK4 JETTA MOD SOFTWARE
Everyone knows bolt-on upgrades paired with a software tune are the fastest ways to add power, but what are enthusiasts running in their cars? Where should new enthusiasts spend their money to get the most enjoyment possible out of their MK4 GTI? Today, we’re looking specifically at upgrades we think every MK4 GTI 1.8T owner should have. Thanks to its availability, affordability, and the aftermarket support offered for this engine, it’s more of a question of where to start rather than what to do. This DIY was preformed on a 1.The Volkswagen MK4 GTI with the 1.8T engine is one of the most commonly modified platforms available. At the bottom of the article there is a segment about twisting the tb 90 degrees for better air flow distribution which I would like to hear some feedback on. Once the TB has been removed you will need to replace the gasket ($2 at Autozone, part # in DIY).Īll part numbers and tools are included in the DIY as well as a little section on cleaning the IAT sensor. With this DIY you do have to remove four screws but I guarantee you will notice a huge difference over just spraying some cleaner in it if your TB does have carbon build up. While it makes the throttle plate look clean and pretty it does not remove any of the built up carbon that is blocking the air flow. Most TB (throttle body) cleaner cans tell you to remove the TB hose, spray inside and you're good to go! I've tested this method and it does not work. Over time the throttle body gets covered in carbon which in turn blocks air flow when it's closed and gives a rough idol.

These tools can be rented for free from auto part stores (more on that here, Doing your own car repairs).
For some of the DIY's specialty tools are needed and they are high priced. Besides for that plenty of great tools can be bought from that store for cheap. I follow a few personal rules for the tools I buy from them, 1) Don't use cheap tools for high torque situations and 2) don't use anything from there that you are depending on to keep you safe, jack stands, ect. Also if you have a Harbor Freight tool store in your area they are great for cheap tools. A one time 10-20 dollar expense for tools that will last a lifetime is worth it compared to dealership labor cost at $110 an hour. As for tools, almost all of these DIY's can be done with normal everyday tools that should be in your toolbox already and if you don't already own the tool, a torx bit set for example, buy it.
