{"product_id":"rainbow-titanium-metal-charge-pipe-upgrade-kit","title":"Rainbow Titanium Metal Charge Pipe Upgrade Kit","description":"The BAVMODS® Rainbow Titanium Metal Charge Pipe Upgrade Kit is engineered to replace the failure-prone OEM plastic charge pipe in BMW G22 M440i Coupe, G23 M440i Convertible, and G26 M440i Gran Coupe models equipped with the B58 Gen 2 (B58TU) engine, covering model years 2021–2025. The factory plastic charge pipe is susceptible to cracking, flexing, or separating under increased boost pressure, particularly in tuned vehicles or during spirited driving. This upgrade offers a fortified solution with its high-strength metal construction.\n\nCrafted with a unique heat-treated rainbow titanium finish, this charge pipe not only withstands extreme under-hood temperatures but also provides a striking visual enhancement with its shifting spectrum of gold, violet, and blue. The interior is precision-machined to promote smoother airflow, minimizing turbulence and pressure loss. This design contributes to faster turbo spool, improved throttle response, and more stable boost delivery, making it suitable for both stock and modified M440i vehicles.\n\nKey benefits of this upgrade include reinforced reliability by eliminating the risks of cracking and boost leaks associated with plastic pipes. Its optimized airflow path ensures efficient boost delivery, while the corrosion and heat-resistant titanium construction guarantees longevity. The kit offers OEM+ fitment, meaning it installs directly using factory sensors, clamps, and couplers. The result is enhanced performance you can feel, with immediate improvements in throttle precision, boost consistency, and turbo response, all while adding a premium, motorsport-inspired aesthetic to your engine bay.\n\nFITMENT: BMW 4 Series – G22 \/ G23 \/ G26 (2021–2025) including M440i Coupe, M440i Convertible, and M440i Gran Coupe (all with B58 Gen 2 \/ B58TU Engine). Compatible with both RWD and xDrive variants across U.S., European, and Asian markets.","brand":"BAVMODS","offers":[{"title":"Default Title","offer_id":52687066628408,"sku":"bmw-g22-g23-g26-4-series-m440i-rainbow-titanium-metal-charge-pipe-upgrade-kit","price":369.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662152316.webp?v=1784880015","url":"https:\/\/store.motormia.co\/products\/rainbow-titanium-metal-charge-pipe-upgrade-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
