Why This Kit Beats Generic "Universal" Solutions
100% Factory Match
3D-scanned from genuine Part 667-499 to ensure identical hose thickness (0.06") and connector alignment – no guesswork.
Unlike universal kits that require cutting, this installs perfectly straight with no modifications.
Turbo-Engineered Durability
High-temperature silicone hoses withstand 350°F engine heat (tested in 500+ hours of real-world use).
Stainless steel fittings resist corrosion from oil/coolant exposure – no more "hose melt" failures.
Prevents common failures: oil leaks, turbo bearing damage, and catalytic converter damage.
20-Minute DIY Repair
Includes all three lines (coolant feed, oil feed, oil return) with pre-attached OEM connectors.
Pro Tip: Disconnect battery before installation to prevent electrical shorts.
Critical Safety & Installation Notes
⚠️ ALWAYS ALLOW ENGINE TO COOL – Hot engine surfaces cause severe burns.
⚠️ Disconnect vehicle battery before starting to prevent electrical damage.
⚠️ Do not overtighten fittings (15-20 ft-lbs max) – crushes hoses and causes leaks.
⚠️ After installation, start engine and check for leaks at idle – if oil/coolant drips, verify line connections.
