Z1 Long Tube Cold Air Intakes 2009-2020 370Z & 2009-2015 G37 – Real +18whp, True Cold Air

Z1 Motorsports Long Tube Cold Air Intakes for the 2009-2015 Infiniti G37 Coupe/Sedan and 2009-2020 Nissan 370Z are built specifically for the VQ37VHR 3.7L engine to eliminate the factory airbox restriction and short ram heat soak by relocating dual massive 6-inch inverted cone, 8-layer oiled cotton gauze filters with Z1 hydrophobic pre-filter sleeves deep behind the front bumper, where they pull 40-70°F cooler outside air instead of 150°F+ engine bay heat, and that dense, oxygen-rich airflow delivers proven 12-18whp gains with 10-15wtq improvements across the mid-range on stock and tuned cars, because every kit uses mandrel-bent 3-inch 6061 polished aluminum tubing for maximum cross-sectional area and laminar flow, CNC-machined billet MAF housings with integrated honeycomb airflow straighteners to keep short and long term fuel trims within +/-5% and prevent lean codes P0101/P0171, 5-ply gloss black reinforced silicone couplers pressure tested to 30psi for boosted applications, 304 stainless T-bolt clamps for a leak-free seal, CNC-cut 304 stainless steel brackets with rubber isolators to prevent cracking from vibration, and fully back-purged TIG welds for clean internal airflow and structural integrity, giving you razor-sharp throttle response, the signature Z1 VQ37VHR induction roar above 4000rpm, and support for 600whp+ on forced induction builds without becoming a restriction, and the complete bolt-on kit includes driver and passenger side intake pipes, two 6-inch filters, two pre-filter sleeves, MAF adapter plates with hardware, all couplers, clamps, brackets, and aluminum splash shields to protect against water intrusion for safe daily driving, installs in 2-3 hours with front bumper removal using basic hand tools, is fully compatible with stock throttle bodies, Z1 ported throttle bodies, OEM or aftermarket upper/lower manifolds, and pairs perfectly with UpRev or EcuTek tuning which Z1 recommends to maximize gains and drivability, and unlike eBay knockoffs that use thin 2.5-inch tubing that necks down and kills flow, undersized 4-inch cone filters that choke the engine, cheap rubber couplers that collapse under vacuum, no MAF straightening so fuel trims swing +/-25% and throw CELs, mild steel brackets that rust and snap, and poor welds full of slag that break off into your motor, Z1 intakes are R&D’d, street and track tested on real G37 and 370Z VQ37VHR platforms since 2009, include step-by-step instructions, and are backed by Z1’s USA-based support team who actually know these cars, so you get real power, perfect fitment, and reliability instead of gambling your engine on fake parts that cost you a motor when they fail.
