K&N Aerosol Air Filter Cleaning Kit provides a simple and effective solution to preserve and maintain your K&N air filter, ensuring it delivers optimal performance for a lifetime. This cleaning kit is specifically designed to clean and restore the airflow efficiency of your reusable air filter, saving you money by eliminating the need to purchase replacement filters.
The K&N Aerosol Air Filter Cleaning Kit includes a powerful degreaser that effectively removes dirt, grime, and contaminants from your air filter. Once cleaned, the kit’s specialized oil is used to recoat the filter, ensuring it continues to trap harmful particles while allowing maximum airflow.
Regular maintenance with this kit not only extends the life of your air filter but also enhances your engine’s performance by maintaining high air flow and exceptional filtration. Easy to use, the K&N Aerosol Air Filter Cleaning Kit is an essential tool for keeping your air filter in top condition.
K&N's drop-in air intake filter is constructed from cotton gauze material between aluminum mesh - this makes for a long lasting, high performance drop-in intake filter. These are very easy to remove and maintain. Turner Motorsport recommends this as one of the first maintenance/modifications you make to your vehicle after you purchase!
K&N's drop in air filters allow increased airflow - dirt and particles stick to the oil on these filters, making them more effective than traditional paper filters in terms of protection. Additionally, K&N believes their filters are more efficient than paper filers - this means more oxygen getting into the engine, allowing vaporized fuel to burn more efficiently and increasing horsepower and fuel economy. The best of both worlds!
Introducing the do88 Intake System for BMW 320i and 330i G20 – Engineered for Maximum Performance!
At do88, we understand that filtration, airflow, and heat management are crucial when designing an intake system for turbocharged engines.
Our intake system is designed to provide the turbo with excellent filtration, an optimized airflow path, and consistently low inlet temperatures. One of the key challenges with the B48/B46 engine is the intake system’s location near the exhaust manifold, which generates intense heat and causes rapid heat soak.
High intake air temperatures (IATs) can significantly reduce engine performance, as hot, less dense air makes it harder for the turbo to build boost efficiently. To address this, our fully sealed intake system minimizes heat exposure and maintains low IATs. However, fully sealed systems can face airflow restrictions due to the factory airbox’s single air feed. We resolved this by adding a secondary air feed and incorporating a heat shield into the airbox design to block heat from the exhaust manifold. The large 7” airbox ensures ample airflow around the filter and accommodates strut braces.
We replaced the stock intake hose with a high-flow 102mm (4”) mandrel-bent aluminum pipe paired with a custom silicone hose. The system also features a custom-designed air filter with tightly woven cotton gauze for exceptional filtration. The filter is washable, reusable, and built for long-lasting performance.
Unlike the stock air filter box and intake hose, which are designed with silencers to reduce turbo and induction noise, the do88 system eliminates these elements. This allows for a more pronounced and engaging turbo spool and induction sound, giving you a truly dynamic driving experience.
