Open the hood of a turbocharged BMW and the parts you notice first are usually the ones you can see. The airbox sits up top, the intake runs toward the turbo, and much of the charge piping disappears from view. Look a little further and the build starts to tell a more interesting story: what the owner chose to keep, what they replaced, and which details they took care of while the car was apart.

FTP Motorsport makes parts for those decisions. The catalog at Extreme Power House includes charge pipes and turbo inlets, along with filters, oil catch tanks and an oil cooler guard. You can start with a filter for a MINI that still has its factory airbox, check out a charge pipe for a newer BMW 5 Series, or look at underbody protection for an M3 or M4. Each part has a different job and a different set of fitment details worth checking before you buy.

Start at the airbox: A direct-fit filter for select MINI models

If you're happy with how the factory airbox sits in the engine bay, the FTP F56 MINI Air Filter is a straightforward option to consider. XPH describes it as a direct-fit replacement element and lists select B38- and B48-powered MINI applications, including the F56 hatchback and F55 five-door. The listing also covers certain F54 Clubman, F57 Convertible and F60 Countryman applications. Check the production range in the fitment list for your specific model.

A replacement element makes sense when you want to keep the factory housing and are already planning an air filter service. If you bought the car with an aftermarket intake installed, take a look at the housing before you order. A filter shaped to fit the original box may be different from the one in your current intake. It takes a minute to check and can save you from ordering a part for an airbox the car no longer has.

On the boost side: B48N and B58 Gen 2 charge piping

The FTP B48N Gen 2 Charge Pipe, part SG71488, is an aluminum replacement for BMW part 13 71 5 A71 433. XPH lists it for B48N applications including the G60 520i and 530i, as well as select G45 X3 models. It comes with the O-rings and retaining clips already installed. That's useful information to have before the car goes on the lift, especially if you're ordering the pipe for a specific shop appointment.

For a six-cylinder example, the FTP B58 Gen 2 Charge Pipe, part SG71444, is listed for select BMW applications and the A90 Toyota GR Supra with the 3.0L B58. XPH describes aluminum construction, three-inch tubing and three-ply silicone couplers. The listing has a model selector, so choose the version for your car and confirm the factory part number against the application.

A charge pipe carries compressed air on the boost side of the system. When browsing parts, use the product photos and the factory reference to identify the section you want to replace. A similar engine name can appear on an intake pipe or a charge pipe, even though they sit in different places and have different connections.

Under the engine cover: The details that matter on a catch tank install

FTP also offers the G20 B48 Oil Catch Tank, part SG80056, for the B48-powered G20 318i, 320i and 330i listed by XPH. The tank uses an internal baffle arrangement to separate oil from air. The body is black anodized aluminum, and the design mounts on the cooler side of the engine bay.

The key detail is in the listing title: the engine cover needs to be cut for installation. If you care about preserving the original cover, discuss that before committing to the kit. Ask your installer where the tank will sit, how you'll reach it for inspection and draining, and how the hoses will be routed around the other parts you've installed. That makes it easier to decide whether this particular setup suits the way you maintain the car.

Below the bumper: A dry carbon guard for the G8x oil cooler

On a G80 M3 or G82/G83 M4, the oil cooler is mounted low and can be exposed to debris from below. XPH lists the FTP Dry Carbon Skid Plate Oil Cooler Guard for the 2021+ G80 M3 and 2021+ G82/G83 M4. The design combines a dry carbon panel with a grille opening intended to allow air to reach the cooler while adding a barrier against direct debris impacts.

This is the kind of upgrade to consider while planning other work near the front bumper or undertray. If you've fitted a front lip, aftermarket underbody panels or other hardware in the area, show your installer how everything is currently mounted. Ask them to check the shared space and mounting points before booking the job, particularly if the car has already been lowered.

Build your parts list around the car in front of you

Start with the model, chassis, engine and production date. For a pipe, add the factory part number if you can find it. For a filter, check the airbox. For an oil cooler guard, look at the panels already under the bumper. These checks help narrow the catalog to the pieces that fit the car you've built so far. They also give you a clear list to hand your installer if you're combining the work with routine service.

Whether you're looking after a daily-driven MINI or planning the next round of work on a BMW M car, the FTP range gives you practical places to start. Shop FTP Motorsport at Extreme Power House to compare parts and check fitment for your next upgrade.
