Universal Performance Parts for Japanese Cars

Most of our universal performance parts install with common hand tools including socket sets, combination wrenches, screwdrivers, and pliers. Cold air intakes and strut tower braces require only basic tools and can be installed in 60-90 minutes by DIY enthusiasts with moderate mechanical experience.

Fuel system components like adjustable fuel pressure regulators may require specialized tools such as fuel line disconnect tools specific to your vehicle manufacturer. Racing seat bracket installation benefits from having a torque wrench to properly tighten mounting bolts to factory specifications. We include tool lists with every product’s installation instructions.

Horsepower gains from our universal cold air intake systems vary based on your vehicle’s engine configuration and existing modifications. Naturally aspirated four-cylinder Japanese engines typically gain 8-12 horsepower with corresponding torque increases of 7-10 lb-ft. Turbocharged applications often see larger improvements of 12-18 horsepower due to reduced intake restriction and lower inlet temperatures.

These gains represent average results from independent dynamometer testing across multiple vehicle platforms. Your specific results may vary based on factors including elevation, ambient temperature, fuel quality, and overall engine condition. Beyond peak horsepower numbers, most drivers notice improved throttle response and smoother power delivery throughout the RPM range.

Our DNA Motoring universal cold air intake systems are designed to maintain factory emissions equipment including mass airflow sensors and PCV connections. The systems do not eliminate or bypass emissions controls and should pass visual inspections in most states. However, emissions regulations vary by state and local jurisdiction, so we recommend checking your specific area’s requirements.

Performance modifications including seat brackets, strut tower braces, and chassis components typically do not affect emissions compliance as they don’t alter engine management or exhaust systems. Fuel pressure regulators may affect emissions if adjusted outside factory specifications, so proper tuning is recommended when making fuel system modifications.

Cold air intake systems require periodic filter cleaning to maintain optimal performance. Our reusable cotton gauze filters should be cleaned and re-oiled every 30,000-50,000 miles depending on driving conditions. We recommend annual inspection of all intake mounting points and couplers to ensure clamps remain tight and silicone couplers haven’t developed cracks.

Chassis components like strut tower braces and seat brackets require minimal maintenance beyond periodic inspection of mounting hardware. Check bolts for proper torque annually and inspect for any signs of corrosion on steel components. Fuel pressure regulators should be inspected for leaks every 6 months and the pressure gauge verified for accuracy against a known-good external gauge.

We accept returns on uninstalled parts within 30 days of purchase in original condition with all packaging and hardware included. Return shipping costs are the customer’s responsibility unless the fitment issue resulted from an error in our compatibility information. We recommend thoroughly verifying fitment and measuring mounting points before installation to avoid return shipping expenses.

Installed parts showing no signs of manufacturer defects are not eligible for return, as we cannot verify whether fitment issues resulted from vehicle modifications or installation errors. If you’re unsure about compatibility with your specific vehicle, contact our technical support team before ordering to discuss your application and verify fitment.

Under the Magnuson-Moss Warranty Act, vehicle manufacturers cannot void your entire warranty simply because you’ve installed aftermarket parts. However, if an aftermarket part directly causes damage to a factory component, the manufacturer may deny warranty coverage for that specific repair. For example, an improperly installed cold air intake that allows water ingestion and causes engine damage would likely not be covered.

We design our DNA Motoring universal parts to install without permanent modifications to factory components, allowing reversal to stock configuration if needed for warranty service. We recommend documenting the condition of factory parts before installation and retaining all original components in case you need to reinstall them for warranty work.
