The world´s first model adapted inlet hoses for Porsche 992 Carrera, -S, -GTS!

Background
The inlet system on the Porsche 992 is completely revised from previous versions. Is has a completely different layout but the principle is of course the same. As ever – as cold air and as much of it as possible is what brings effect and elevates the driving experience behind the wheel.

Key figures
- More air to your engine, less backpressure and better airflow!
- Airflow at 0,175 bar / 2,54 psi pressure drop: 775 CFM (667 CFM), 16 % higher! See diagram under the product pictures.
- 3D, freeform designed inlet hoses made from the finest silicone.
- CNC-machined turbo inlet adapters.
- Fits towards OE or do88 air filter box (66 mm).

Considerations
The efficiency of a turbocharged engine is under direct influence of the inlet air temperature (IAT) and the backpressure in the system. A crucial aspect, yet often overlooked, is having sufficient airflow before the compressor to avoid surge. Less vacuum and colder air enables the turbo to produce a larger mass which in the end means more air to the intake – summing up, this means noticeable power gains. There are great power wins to be earned with a good induction system! Throughout our years in this business, with countless hours of evaluation and development, we have seen the coherent connection in between IAT, sufficient airflow to the compressor, and the impact this has on the output. The Porsche 911, with its twin turbochargers and vast tuning potential, is always begging fore more air. That was always the case with the 911 – it still is!

do88 turbo inlet hoses
We started the development by 3D-scanning the entire designated area on the car. This allowed us to work in a sensible manner, with the products in our CAD-environment using SolidWorks. The entire air filter system is optimized for airflow and radiuses and angles are reworked many times to achieve the best result! The finished product is verified with both Computer Flow Dynamics (CFD) as well with our Superflow SF1020 flowbench. All efforts are made to offer real and trustworthy data for you as a customer.

The kit comes with hoses in a textured black finish, CNC-machined adapters towards the turbos and top-quality, black hose clamps. The hoses are adapted to the OE air filter boxes, or the do88 air filter system with 66 mm connections.

Please note that these hoses provide a good upgrade. We consider them a solid first step in the refinement of your Porsche 911. However, we´d like to underline the fact that the best effect is achieved when these hoses are used in junction with the do88 air filter system. With that upgrade, all restrictions before the turbo inlet are eliminated and the turbos can reach their full potential!

About this Cold Air Intake

The do88 DO88-KIT212ST-OE-66 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.
