The stock airbox is restrictive and the panel filter obstructs a smooth flow. Yet, with the addition of a boost controller and tune, dynos have shown gains of up to 56whp! Pretty astonishing for an otherwise stock car.ĭrivers will also notice a decrease in spool time and increase in throttle response with an Evo X intake upgrade. With just the intake and tune, gains will likely be capped at 25whp at most. The huge variable in difference comes from also adding a boost controller. Evo X drivers can expect between 5-56whp from installing an intake on their car. The biggest factor in a Lancer Evo X intake upgrade is the power increases. There are many benefits to an Evo X intake upgrade, including: The airbox does cost significantly more, however. However, practically, there is very minimal difference between an airbox and a heat shield. It also does not retain the factory intake scoop, which makes it harder to grab cool ambient air from outside the engine bay. The heat shield leaves the filter mostly open and only blocks heat and turbulence from the bottom. It allows for reduced temperatures and more consistent airflow, and it gives more stable MAF scaling and calibration. The airbox is the superior of the two, because it fully encloses the filter from the motor. Heat Shield vs AirboxĪs far as performance intakes go, they also fall into two general types: either they have a heat shield or a full airbox. That means they are not true cold air intakes, but they still offer reduced intake temps when compared with most short rams. Most Evo X intakes will keep the filter in the same location as the stock airbox. Some people will refer to performance intakes on the Evo X as a cold air intake, but that’s not entirely correct. Unfortunately, the location of the filter on short ram intakes makes them susceptible to the hot air of the engine bay.Ĭold air intakes reroute the filter to either the bottom of the engine bay or near the headlight or fender. They are designed to be as nonrestrictive as possible to allow for max air flow. Short rams have less piping and deliver the air to the engine quicker. There are two main types of Evo X intake upgrades, either short ram or cold air. Colder air has more oxygen than hot air, so it increases power and improves gas mileage. What is important about intakes is making sure they are able to deliver the coolest air available to the engine. Once air enters the turbo, it gets compressed and fed through the intercooler and into the engine. On turbo cars, the intake connects directly to the compressor side of the turbo. The large cone shaped filter increases the amount of air that can be brought into the engine compared with the stock airbox, and the design of the piping allows for less turbulent and more efficient airflow. Not only will add horsepower and torque, but it also improves gas mileage and turbo spool. We will discuss benefits, power gains, cost, and more.Ī performance intake is one of the most common upgrades on the Evo X for many reasons. This new guide will cover everything you need to know about an Evo X intake upgrade. Previously, we have looked at the Top 7 performance mods for the Evo X as well as Evo X coilover upgrades. The Evo X’s 4B11 responds very well to intake upgrades. It makes sense why not only are they relatively easy to install and cheap, but they also add power and increase sound. Performance intakes are often one of the first upgrades that Evo X owners will do when starting to mod their car. It is one of the most modable engines created, and it responds very well to bolt-on upgrades, like intakes. The 4B11 engine powered the 10th generation Evolution, or Evo X. The Evolution started as a rally variant of the Mitsubishi Lancer in the early-1990s, and it made its debut in America in 2003. The Mitsubishi Evo X is one of the most popular and iconic tuner cars in history.
