Yes. Kami Speed is an authorized BLOX Racing dealer sourced directly from BLOX. BLOX Racing explicitly warns buyers on their own homepage to only purchase from authorized dealers due to widespread counterfeiting — fake BLOX throttle bodies, intake manifolds, shift knobs, and engine hardware circulate constantly on eBay, AliExpress, and unverified Marketplace listings. Counterfeit BLOX parts often use substandard materials, incorrect dimensions, and inferior CNC tolerances that fail under boost or at high RPM. Every BLOX product we sell ships in original BLOX packaging with full warranty intact and is verified through BLOX's authorized dealer supply chain. If a price seems too good to be true, it's almost certainly counterfeit.

Most in-stock BLOX Racing items ship within 1 to 3 business days from US warehousing. Popular Honda applications — throttle bodies, intake manifolds, shift knobs, valve springs, coilovers for 92-00 Civic/94-01 Integra, K-series accessories, and 10th/11th gen Civic parts — are typically stocked. Made-to-order items, less common LS-VTEC conversion kit configurations, and some Tuner Series internals may have a 1 to 2 week lead time from BLOX. We confirm exact availability and ETA at order placement.

BLOX Racing products carry the manufacturer's warranty against defects in materials and workmanship for unused, properly installed components. Returns on unused, uninstalled BLOX parts in original packaging are accepted within 30 days. Once a part has been installed — throttle bodies bolted to manifolds, coilovers mounted to a chassis, valve springs pressed into a head — it is no longer returnable, since aftermarket performance parts cannot be resold as new once they've been on a car. Defective products are covered directly by BLOX, and Kami Speed handles RMA processing on your behalf. Track use, racing, and engine failures from incorrect installation or supporting mods are not covered under BLOX's standard warranty.

BLOX Racing engineers their catalog primarily around Honda B-series (B16, B18, B20), D-series (D15, D16), H-series (H22, H23), F-series (F20, F22, F23), and K-series (K20, K24) engines, plus the chassis those engines came in — 88-00 Civic, 90-01 Integra, 94-01 Integra, 92-96 Prelude, 97-01 Prelude, 02-06 RSX, 02-05 Civic Si, and into the modern 06-15, 16-21, and 22+ Civic and Type R platforms. Most BLOX engine parts list specific engine compatibility, and chassis parts list specific year ranges. If you're swapping engines (LS-VTEC, K-swap into older chassis, etc.), BLOX makes conversion-specific parts but compatibility depends on your exact combination. Check the fitment on each product page or contact us with your build details and we'll confirm.
