BMC FB750/04 At a Glance

• Filter type: Washable replacement air filter set
• Package contents: 2 air filters
• OEM cross reference: Porsche 98111013000
• Main applications: Select Porsche 981 flat-six models and select Porsche 982 4.0L flat-six models

Which Porsche Models Use the BMC FB750/04?

The FB750/04 is best understood as a Porsche mid-engine flat-six filter set. BMC lists applications across the 981-generation Boxster and Cayman, plus select 982-generation 718 models equipped with the 4.0L naturally aspirated flat-six engine.

This distinction matters because not every vehicle wearing a 718 badge uses the same airbox configuration. The 982 718 2.0L and 2.5L turbo flat-four models should not be grouped together with the 4.0L GTS, GT4, and Spyder applications unless fitment has been confirmed by OEM reference and application data.

BMC FB750/04 Fitment Guide

Use the table below as a guide, then confirm your vehicle details before ordering. The key OEM reference to compare is 98111013000.

Fitment note: Porsche fitment can vary by market, production date, trim, airbox configuration, and replacement part history. Always confirm your OEM air filter reference before ordering. If you are unsure, contact European Performance Filters before purchasing.

Does FB750/04 Fit Every Porsche 718 Boxster or Cayman?

No. This is the big point.

The Porsche 718 name can refer to different engine families depending on model year and trim. Some 982 718 models use 2.0L or 2.5L turbocharged flat-four engines, while the GTS 4.0, GT4, and Spyder use a naturally aspirated 4.0L flat-six. The BMC FB750/04 application data is centered on the listed flat-six applications, not every 718 model.

If your car is a 982 718 2.0L or 2.5L turbo model, do not assume FB750/04 is correct just because the vehicle is a Boxster or Cayman. Confirm by OEM air filter number, engine, and airbox before ordering.

Why Upgrade From a Disposable Paper Filter?

The factory-style disposable paper filter is designed to meet broad OEM requirements for filtration, cost, service life, and everyday use. A BMC replacement filter is designed for enthusiasts who want a washable, reusable filter that supports improved airflow while retaining OEM-style fitment inside the factory airbox.

The FB750/04 does not require a custom intake conversion, airbox modification, or tuning when used as a direct replacement in the correct application. It is intended to replace the compatible factory air filter set while preserving the original airbox layout.

What Makes the BMC FB750/04 Different?

BMC replacement filters use oiled cotton gauze filter media and are designed to be washed and regenerated with the proper BMC service kit. For Porsche owners who keep their cars long-term, that makes the FB750/04 a useful alternative to repeatedly replacing disposable filters.

• Washable and reusable: Designed to be cleaned and re-oiled instead of discarded after each service interval.
• OEM-style fitment: Designed to install in the compatible factory Porsche airbox.
• Performance-focused filtration: Supports improved airflow while maintaining filtration for street and performance use.
• Two-filter set: FB750/04 includes the filter pair needed for the listed applications.

Will the BMC FB750/04 Add Horsepower?

A high-performance replacement filter can help reduce intake restriction compared with a dirty or restrictive filter, especially as airflow demand increases. However, exact power gains depend on the vehicle, airbox design, filter condition, engine management, temperature, altitude, and supporting modifications.

The realistic benefit is not a magic horsepower number. The value is a washable, reusable, performance-focused filter set that supports airflow in the factory intake system while maintaining a clean OEM-style installation. That is the honest answer — no dyno fairy dust required.

Installation Notes

The FB750/04 is designed as a direct replacement filter set for compatible Porsche factory airboxes. Installation difficulty can vary by model and access around the airbox, but the filter set does not require tuning or permanent modification when installed in the correct application.

For general installation guidance, visit the BMC air filter installation guide.

Cleaning and Maintenance

The BMC FB750/04 is washable and reusable. When service is needed, clean and re-oil the filters using the correct BMC cleaning kit. Avoid over-oiling, and allow the filters to dry fully before applying oil and reinstalling them.

You can find the correct maintenance product here: BMC Wash Kit WA250-500. For detailed service instructions, read the BMC air filter cleaning and recharge guide.

Who Should Buy the FB750/04?

The FB750/04 makes the most sense for Porsche owners who have confirmed fitment and want a washable replacement filter set for a compatible 981 or 982 flat-six application. It is especially relevant for owners of 981 Boxster/Cayman S, GTS, Spyder, and GT4 models, along with 982 718 GTS 4.0, GT4, and Spyder applications listed for this filter.

If you are simply searching by “718 Boxster filter” or “718 Cayman filter,” slow down and confirm your engine first. The badge alone is not enough.
