This month’s spotlight lands on a compact powerhouse that’s been turning heads for all the right reasons - BIGBOI Car Care’s new Audi RS3. Already a performance benchmark in its class, this car has now received a carefully curated suite of upgrades to enhance cooling, handling, and overall driving precision.
Wagner Tuning EVO3 Intercooler Kit + Boost & Charge Pipes
Under the bonnet, we’ve fitted the Wagner Tuning EVO3 Competition Intercooler Kit, an industry-leading cooling upgrade engineered for efficiency and performance. With a 1,920 cm³ core volume and high-density tube-fin construction, the EVO3 delivers significantly lower intake temperatures, even under heavy load or repeated high-speed pulls.
The result? Denser, cooler air reaching the combustion chambers - translating to more consistent power delivery, reduced heat soak, and greater reliability under boost. The precision-machined aluminium end tanks also ensure maximum durability and flow stability, while keeping pressure drop to a minimum.
Completing the system, Wagner’s Boost and Charge Pipe Kit replaces the restrictive OEM plastic piping with lightweight mandrel-bent aluminium. This not only improves airflow response but also removes a common weak point on the factory setup. Reinforced silicone couplers keep everything sealed tight, maintaining consistent boost pressure across the rev range.
Eibach Pro-Kit Springs + ECS Wheel Spacers
Bringing the RS3’s stance and dynamics to the next level, a set of Eibach Pro-Kit Lowering Springs has been installed - reducing ride height by 0.7 inches at the front and 0.5 inches at the rear. This subtle but effective drop sharpens steering response and cornering stability while preserving the car’s daily drivability.
Paired with ECS Tuning 15mm Wheel Spacers and Black Ball-Seat Bolts, the stance has been widened for a more aggressive footprint and improved road presence. The combination gives this RS3 a confident, planted look while subtly refining its handling balance.
Pipercross Drop-In Air Filter
To round things out, a Pipercross drop-in performance air filter enhances breathing efficiency. Constructed with multi-layer foam for optimal flow and filtration, it ensures the 2.5 TFSI engine draws in cooler, cleaner air - helping the car breathe freely under boost while maintaining superior protection against dust and debris.
In Good Company
This RS3 is the latest addition to the BIGBOI Car Care family, joining an elite group of beautifully presented, high-performance vehicles that embody passion, precision, and personality. Next step is going to be tuning!
