Reasons Why Car Buyers Should Consider Plastic Intake Manifolds over Metallic Manifolds
A few decades ago, the use of any other material in the car engine apart from metal was a far-fetched thought. However, in recent years, engine suppliers and automakers have discarded this old engineering rule by embracing plastic components to decrease automobile weight. Under your car bonnet, you are likely to find plastic intake manifolds made with a blend of nylon and other materials. Despite the many challenges that faced the plastic intake manifold system in the early years, current systems have improved designs and composites. This article highlights four reasons why buyers should consider this type of intake design.
Resistance to Elements -- The world inside a car bonnet is a harsh place characterized by continuous vibration and elevated temperatures, which generate stress on many engine parts. Engine components are in constant contact with brake fluid, grease, transmission fluid, water, petrol, ice, dirt, salt, and dust among other elements. Furthermore, extreme temperature fluctuations often affect metallic engine components. The plastic air intake manifold withstands all these fluctuations, and because of its wear resistance quality, it could fit in any terrain and environment.
Cost Savings -- The corporate-average fuel economy (CAFE) guidelines require that without giving up on cost and safety measures, automakers ought to maximize their standard fuel economy by at least 40 percent before the year 2020. With this demand for enhanced fuel efficiency, automotive engineers are exploring the use of plastics to save on these costs. Engineers have designed plastic manifolds to aid in downscaling engines while improving fuel economy. Due to this quality, plastic intake manifolds are a smart purchase.
Durability, Strength and Weight -- Most of the air intake manifolds made of polymeric materials are lighter and durable than metallic designs. There is an ongoing cascade, by automakers across the globe, to reduce the weight of vehicles. Molding air intake manifolds from plastics, instead of metal, ensures a significant reduction in automotive weight. Such a reduction goes a long way in saving a potential car buyer significant fuel costs. Because of their durability, plastic manifolds are also designed to endure all pressures and loads under the bonnet for a lost time without the need for replacement. Engineers optimally blend fiberglass with plastic to offer improved strength and durability.
Sound Dampening -- Thicker construction of plastic intake manifold systems, fortified by aluminum and fiberglass, offers superior load-bearing and sound-deadening acoustic capability. The acoustic quality eradicates rasping and unnecessary engine noises. Additionally, newer versions are supported by silicone gaskets that facilitate enhanced contraction between different components, thus eliminating vibrations. This quality makes you have a smooth ride without the annoying noise and vibration from under the bonnet.
