AIRTEC Front Mount Intercooler FMIC Upgrade Kit for Audi S3 8L 1.8T Quattro - Uprated Charge Air Cooler, 60mm Single-Pass Core, Cast End Tanks, Direct-Fit Bolt-On, Pro-Series Black or Silver, Silicone Hose Set, SMIC Delete, Heat Soak Fix

Uprated Charge Air Cooler Kit for Audi S3 8L 1.8T Quattro by AIRTEC

Chase cooler intake temps and dependable performance with AIRTEC’s uprated cooler for the Audi S3 8L 1.8 turbo Quattro. This direct-fit solution replaces the restrictive twin side-mounted units with a straight-through 60 mm core and smooth cast tanks, giving stronger mid-range punch, rapid heat recovery and confidence for fast road and track use.

Proven on the dyno at AMD Tuning Essex, a Stage 1 remapped 1.8T saw a 12 bhp uplift through the mid range alongside a major reduction in charge temps. We run this on our own builds and our customers consistently report crisper response and repeatable pulls with far less heat soak.

Why this cooler is a smart upgrade

• High efficiency single-pass 60 mm core for excellent thermal control under sustained load
• Cast end tanks designed for smooth airflow and strength with fewer welds
• Replaces both factory side-mount units to maximise frontal cooling area
• Ideal for tuned 1.8T cars used on spirited road driving and track days
• Outstanding performance per pound without the compromises of budget options

What is included

• Large AIRTEC intercooler with 60 mm single-pass core and cast tanks
• Premium 4 or 5 ply silicone hoses with no internal joins for smoother flow
• Stainless steel Jubilee clips
• Stainless brackets for horn and ambient temp sensor with AIRTEC logos
• All required fixings plus detailed fitting instructions

Fitment details

• Designed for all Audi S3 8L 1.8T Quattro models
• Retains the OE crash bar with only minor trimming as per the instructions
• Keeps original fog lights
• No cutting to visible bumper or fog grilles
• Typical install time 2 to 3 hours depending on experience

Dyno-proven results

AMD rolling road testing on a Stage 1 remapped car showed:

• Stock coolers: inlet 128°C, outlet 49°C with power falling as heat built up
• AIRTEC cooler: inlet 126°C, outlet 23°C and a 12 bhp gain in the mid range

Figures recorded on a Seat Leon Cupra R that uses the same cooler and pipework as the AIRTEC S3 kit, so you can expect comparable results on your S3 8L.

Finishes and options

• Pro-Series satin black or natural silver finish
• Silicone hose colours available in red, black or blue
• AIRTEC 3 year unlimited mileage warranty
