The E30 M20 is a beloved model among car enthusiasts, known for its performance and tuning potential. One of the most popular modifications for this engine is the installation of an aftermarket intake system. In this article, we will explore the power gains, costs, and considerations involved in upgrading the intake on your E30 M20.
Understanding Aftermarket Intakes
