About store

GSTP Auto Parts is a direct-to-consumer and automotive aftermarket supplier specializing in specialty performance hardware, fuel/fluid delivery systems, engine fabrication accessories, and dedicated mechanic tools. Catering to DIY garage builders, motorsport hobbyists, and professional tuning technicians, GSTP positions itself as a cost-efficient alternative to premium aftermarket racing brands (such as Earl’s Performance, Vibrant, and Aeromotive). The platform delivers precision-machined plumbing, intake, and exhaust components required for engine swaps, forced induction builds, and custom performance plumbing.

From an automotive mechanical engineering, material fabrication, and component design standpoint, GSTP segments its inventory across five core functional areas:

  • Fuel & Fluid Delivery Plumbing: AN-size braided hoses (CPE and PTFE inner cores wrapped in stainless steel and high-tensile nylon braid) designed to safely convey high-pressure fuel, E85 ethanol, oil, and coolant without vapor permeability. The line includes high-flow inline fuel filters, fuel pressure regulators, check valves, and comprehensive collections of 37° AN flare adapters (-4AN to -12AN) in straight, 45°, 90°, and 180° swivel configurations.

  • Engine Bay Fabrication & Oil Catch Systems: Baffled aluminum oil catch cans (preventing blow-by vapor and carbon buildup in direct-injection and turbocharged engines), sheet-metal and cast intake manifolds (such as 102mm cathedral-port LS-series intake assemblies), aluminum coolant overflow reservoirs, and aftermarket valve cover accessories.

  • Exhaust & Turbo Plumbing Systems: Stainless steel exhaust cutouts (pneumatic and electronic valve setups), V-band clamp flanges, intercooler silicone couplers, and exhaust wrap thermal insulation.

  • Specialty Installation & Fabrication Tools: Manual and hydraulic tubing beader rollers (for creating bead retention edges on aluminum intake and intercooler piping), PTFE/CPE fuel line fitting assembly presses, valve spring compressors, and pipe reamer kits.

  • Chassis, Drivetrain & Suspension Hardware: Billet transfer case linkage kits, polyurethane/grommet bushings for heavy-duty domestic pickup platforms (Dodge Ram, Ford, Chevy), and engine mount reinforcement brackets.

Operationally, GSTP Auto Parts services North American and international orders through established US-based regional fulfillment warehouses. Domestic delivery typically processes within 1 to 2 business days, offering standard 3- to 7-day transit via major domestic ground carriers. The direct storefront provides a 30-day return policy on unused components, dedicated customer support via email, and free domestic shipping on qualifying cart thresholds.

Promotional Codes & Offers

 

  • Official Site Offers: Direct clearance discounts (up to 30%–40% off select intake manifolds, tubing rollers, and braided line spools), bundle savings on multi-piece AN fitting kits, and free standard domestic shipping directly at www.gstpautoparts.com/.
