I put the whole mechanism in question. The lid is tightened with magnets, and a spring. If the hood is turned on, a certain pressure must first be logically constructed to overcome the magnetic force and spring force to open the lid. If the magnetic force only overcome the spring force, which alone is then lower. But still the same pressure or at least approximately the same pressure is applied which was required to overcome the magnetic and spring shoots the lid on downright and bangs against the stop / retaining lugs. Or so it is likely to happen in any hood, no matter how strong the engine hood.
CONCLUSION: Give the money instead for a simple significantly more favorable Louvre made, or if it may be slightly more expensive to invest in an electrically controlled system - there's about 385 from, - EUR. However, the money for FlowStar is kicked out!
