do88 proudly presents the Intake System for Audi RS6 RS7 C8, engineered for high power outputs!

Filtration, airflow and heat are the key considerations when designing a new intake system for a turbocharged engine. Upgrade your Audi RS6 or RS7 C8 with the do88 LF-300 High-Flow Intake – perfect for your high-performance build.

Better Performance Starts with More Air

This intake system improves airflow, helping your engine breathe better. More air means more power, improved throttle response, and better overall engine performance.

Why Upgrade?

A turbocharged engine performs best when the air is cool and flows with minimal restrictions and low back pressure. The stock intake can create restrictions on a tuned engine that raise air temperature and reduce power. The do88 intake system solves this by reducing back pressure and vacuum, letting your turbos work more efficiently. The result? Strong power gains and a more responsive engine.

Designed to Perform – and Look Good

Not only does this system improve performance, but it also gives your engine bay a premium look. The carbon fiber airbox, silicone hoses, and aluminum casting turbo inlets offer both best performance and look.

Complete Plug-and-Play Kit

This intake replaces the factory setup and includes everything you need:

  • Carbon fiber airbox (both bottom and lid)
  • High-flow BMC air filter
  • Enlarged silicone hoses
  • Larger turbo inlets with adapter rings to fit both stock and hybrid turbos
  • All hardware for easy installation

Optional Add-On: Air Straighteners

As an option for this intake system, we offer OE-style air straighteners designed to fit the do88 turbo inlets. To our knowledge, we are the only aftermarket supplier providing this solution. These air straighteners help preserve OE-like power characteristics across the full RPM range and help maintain their durability.

Manufactured using metal 3D printing, these air straighteners introduce slightly more airflow restrictions compared to the standard radius adapter rings included with the kit. They are available in two sizes to suit either OE turbos (Ø54mm) or hybrid turbos, such as the TTE 1020 and Power Division PD1200 (Ø60mm).

Key Features:

  • Up to 42% lower pressure drop at the turbo inlets
  • 78% larger turbo inlets (Ø80mm)
  • Adapter rings included making the kit Plug-and-Play with OE turbos or hybrid turbos, such as the TTE 1020 and Power Division PD1200 (Ø60mm).
  • 57% larger airbox outlets in the air box lid
  • BMC high-flow air filter, washable and regenerable for optimum performance and long service life.
  • Reduced pressure drop and strain on factory components compared to OEM.
  • Turbos spool faster and operate more efficiently
  • Aggressive induction sound
  • Compatible with most future mods, i.e., turbo upgrades.
  • Made with high-quality carbon fiber
  • UV- and heat-resistant glossy clearcoat

About this Cold Air Intake

The do88 LF-300-S-WOE air intake system replaces the factory airbox and intake tube to let the engine breathe more freely. Intakes typically bring a sportier induction sound and can improve throttle response, especially on turbocharged engines.

Frequently asked questions

How much power does an intake add?

Gains vary with the engine and are usually modest on a stock car; turbocharged engines and cars with other modifications tend to benefit more. Many buyers choose an intake as much for the sound and response as for power.

Is this intake legal in California?

In California and states that follow its rules, an aftermarket intake must have a CARB Executive Order (EO) number for the specific vehicle to be street legal. Check the product details for an EO number before buying for road use in those states.

Will an intake cause a check-engine light?

A quality intake designed for your car should not. Problems usually come from a poorly sealed connection, a damaged sensor, or over-oiled filters contaminating the mass air flow sensor.

How do I maintain the filter?

Inspect it regularly. Reusable filters can be cleaned and, if they are oiled, re-oiled lightly using the maker's kit. Dry filters can be cleaned or replaced according to the maker's instructions.

How do I make sure this air intake system fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
