While many stock throttle bodies are tuned for peak horsepower at high RPMs, this can sometimes compromise performance in varied riding conditions. The ProX Velocity Stack addresses this by optimizing airflow to the engine.\n\n This alloy tube is engineered to be installed within the throttle body of your EFI system. Its lightweight construction and specialized design work to improve the engine's low-end power and torque, particularly noticeable at lower throttle openings. This translates to significantly improved drivability and increased torque in the lower rev range, where it is most needed for off-road riding.\n\n### Key Features:\n\n \n- Designed to improve low-end torque and drivability.\n \n- Optimizes airflow for EFI systems.\n \n- Lightweight alloy construction.\n \n- Specifically developed for Electronic Fuel Injection systems.\n \n- Aims to enhance performance at lower RPM ranges.","weightGrams":null,"fitments":[],"collections":[{"name":"Carburettor & Intake","url":"https://www.2brosparts.com/api/agent/collection/GB/carburettor-intake"}],"links":{"page":"https://www.2brosparts.com/products/velocity-stacks-crf250-crf450-prox-38vs1001","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/f1bc97be7d48:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/f1bc97be7d48:1"}},"market":{"country":"GB","countryName":"United Kingdom","locale":"en-gb","currency":"GBP","exchangeRateFromGbp":1,"pricesIncludeUkVat":true,"checkoutTax":null,"delivery":[{"name":"Standard","description":"Orders £15.00–£59.99 · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":4.99,"formatted":"£4.99"},"free":false,"minimumOrder":{"amount":0,"formatted":"£0.00","gbp":0},"weightGrams":null},{"name":"Standard","description":"Orders £60.00 and up · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":0,"formatted":"£0.00"},"free":true,"minimumOrder":{"amount":60,"formatted":"£60.00","gbp":60},"weightGrams":null}],"storeUrl":"https://www.2brosparts.com"},"navigate":{"start":"https://www.2brosparts.com/api/agent","search":"https://www.2brosparts.com/api/agent/search/GB/{words+joined+with+plus}"},"howToBuy":{"summary":"Build a basket for the shopper and give them one checkout link.
