CUSTOM UPGRADE

Enhance your vehicles performance with TW Auto's

custom upgrades for your ride.

More Power & Torque: Cooler, denser air means more oxygen, leading to more efficient fuel burn and increased horsepower/torque.
Improved Throttle Response: Better airflow makes the engine more responsive to acceleration.
Aggressive Sound: A more satisfying, sporty engine growl during acceleration.
Better Fuel Economy: More efficient combustion can lead to better gas mileage.
Long-Term Savings: Reusable filters save money over time compared to disposable factory filters.

Downpipes: Connects turbo (if applicable) to the rest of the exhaust; high-flow versions reduce backpressure.
Catalytic Converter: High-flow or sport cats improve flow; removing it (decat) boosts power but raises emissions & legality issues.
Piping: Larger diameter pipes and smoother bends reduce restriction.
Muffler/Resonator: Performance mufflers alter sound and flow; some systems use straight-through designs.
Tailpipes: Change the look and sound, with various tips and finishes available.

Increased Power & Torque: Faster exhaust flow frees up horsepower and torque across the RPM range.
Improved Fuel Economy: Better engine breathing means less work, potentially boosting MPG, especially during cruising.
Better Engine Cooling: Efficient gas expulsion helps regulate engine temperatures.
Enhanced Sound: A deeper, more aggressive exhaust note is a common result.
Lighter Weight: Steel headers are lighter than heavy cast-iron stock manifolds.

Increased Power & Torque: Cooler, denser air means more oxygen for better combustion, increasing power output.
Prevent Heat Soak: Larger cores dissipate heat better, maintaining performance during hard driving (track, towing).
Improved Reliability: Keeps engine components cooler, reducing strain on turbos, pistons, and cylinder heads.
Handle More Boost: Upgraded units, often with metal end tanks, resist the higher pressures of tuning better than plastic stock tanks.

Types of Turbo Upgrades

Big Turbo: Replacing the entire unit with a larger aftermarket turbo for maximum power, but can cause significant turbo lag.
Hybrid Turbo: Upgrades the internals (like the compressor wheel and bearings) within the factory housing for better flow and durability, often creating a balanced performance boost.

Fuel Pump: Replaces the stock pump to deliver higher volumes of fuel at consistent pressure, crucial for supporting more air from forced induction.
Fuel Injectors: Larger or performance injectors deliver finer mist (atomization) for better combustion, supporting higher power demands.
Fuel Lines & Rails: Larger diameter lines and rails ensure fuel reaches injectors without restriction, preventing bottlenecks.
Fuel Filter: A high-flow, high-capacity filter protects upgraded components by removing more contaminants.
Fuel Pressure Regulator (FPR): An adjustable FPR maintains optimal pressure, preventing systems from running too rich or lean at idle or under load.

DPF Delete (Diesel Particulate Filter)
What it is: Removes the DPF, a filter that traps soot from the exhaust.
Better exhaust flow, more power, potential fuel economy gains, avoids expensive DPF regeneration/replacement.

EGR Delete (Exhaust Gas Recirculation)
What it is: Blocks or removes the EGR valve, stopping exhaust gases from being sent back into the intake.
Cleaner intake air, prevents soot build-up, smoother engine, better throttle response, potentially more power/MPG.

Better Flow: Quicker exhaust gas exit reduces backpressure.
Louder/Aggressive Sound: The exhaust becomes significantly louder and deeper.
Increased Power: Less exhaust restriction allows the engine to "breathe" better, potentially increasing horsepower.
