When it comes to naturally aspirated engines, there’s little you can do to increase the power of your car without going hardcore and installing a supercharger or a turbo. That’s a big problem for owners of older cars that are witnessing the rapid advancements in the industry.
For example, the benchmark of the early 2000s, the E46 M3 that is still used as a point of reference when talking about driving dynamics, looks centuries old if you read only its specs written on a piece of paper.
Originally, the car was fitted with an S54 3.2-liter inline 6-cylinder naturally aspirated engine making 343 HP and 365 Nm (269 lb-ft) of torque, revving up to an amazing 8,000 RPM limiter. Even so, the sprint to 100 km/h (62 mph) was done in 5.1 seconds, more than decent for those days.
However, today, you can get a SUV to do those numbers, easily. For example, the new BMW X4, fitted with a DIESEL engine (the xDrive35d, 313 HP and 630 Nm of torque) will do the 62 mph sprint in just 5.2 seconds. That’s a near 2 ton car.
Therefore the obvious solution is supercharging the M3. However, that poses a lot of problems and some people might not be willing to drop the high-revving soundtrack of that car for nothing in the world. They would, however, like some more power.
That’s where you have to become more inventive. How do you get more power from a NA engine? You give it more, colder air. That’s what the guys from VF-Engineering worked on and revealed this week.
Their latest creation is a Cold Air Intake that, when combined with a new ECU software from Hex Tuning, will get you up to 35 extra WHP and 25 extra WTQ. It’s not much but it does make a difference.
According to them, you’ll feel the enhanced throttle response and added power immediately. The entire package will consist of:
