JL Audio StealthMod
Tired of ripping off panels and the rattles that magically occur once said panels are reinstalled just to enhance your stereo system? Designed as a complete audio system upgrade, the JL Audio StealthMod for the ’07-up BMW X5 (E70) eliminates all of the guesswork out of system design and the need for extensive modifications and fabrications. The X5 StealthMod contains a single Stealthbox with a 1-W3v3-2 subwoofer driver that installs beneath the passenger-side cargo floor, one XD700/5 system amplifier with custom mounting bracket, one CL-SSI signal summing interface, one pair of C5-075ct tweeters, and one pair of C5-525-XO crossovers. The system also comes with a complete wiring harness and an illustrated installation and setup instruction book that’s so easy to follow it should be titled “StealthMod for Dummies.” $1,900

One of the biggest design flaws of the factory E46 BMW M3 radiator is the plastic crimp on the end tanks, and over time they start to leak. So why replace a defective part with a flawed factory part that will just leak again? For roughly the same price as a factory replacement, you can get a direct bolt-in replacement from Mishimoto.
The all-aluminum construction and dual-pass design increases cooling capacity by 30 percent, making it the perfect choice for the performance enthusiast or someone looking for maximum reliably. Plus, the Mishimoto radiator is backed by a lifetime warranty. $425
When I first heard about the Sprint Booster for BMW, my mind instantly flashed with the thought of automotive snake oil, just too good to be true—like fuel magnets. Slightly skeptical but always optimistic I immediately ordered one, feeling that there would be some merit with the drive by wire technology being used on modern BMWs. The new unit still acts a go-between, helping the ECU better understand the driver’s true intent with the electronic pedal, plus an added benefit of Off, Stage 1 and Stage 2 settings. So now when you press the go-faster pedal, the engine instantly responds and gives you a more connected feel. $350

Snow Performance Stage 3 Boost Cooler System
The stock intercoolers that come as part of turbocharged BMW engines, to be honest, are a joke. They are extremely inefficient and easily susceptible to heat soak. Snow Performance’s Stage 3 Boost cooler system is a perfect solution for a stock or modified BMW to stave off the dreaded head-induced limp mode during a day of spirited driving. The brains behind the Stage 3 setup is a digital variable mapping controller that creates a methanol delivery map based on user preference and boost pressure. The Snow Performance meth/H20 system can be tuned to generate more horsepower or just help you maintain the factory level of performance lap after lap. Prices start at $760
