Mercedes E63 AMG Performance Parts & Tuning Mods

Top Brands For Mercedes E63 AMG Parts

Mercedes E63 AMG tuning is backed by a strong range of premium aftermarket brands, covering everything from engine upgrades and exhausts to suspension and styling. Below you will find leading manufacturers trusted for quality performance parts and serious AMG mods.

Exterior Styling Upgrades For Mercedes E63 AMG

Give your Mercedes E63 AMG a sharper, more aggressive look with exterior styling mods that match its performance. From body kits, front splitters and rear diffusers to subtle boot spoilers, custom grilles and other visual upgrades, you can fine tune the E63’s presence on the road and create a genuinely unique, motorsport inspired finish.

Handling & Suspension Upgrades

The Mercedes E63 AMG is a heavy, powerful saloon, so the first smart step is tyres and brakes. A set of quality performance tyres with a slightly more aggressive compound will instantly boost grip and confidence on the road and track. Match that with uprated brake pads, braided lines and high-temp fluid, and you get stronger, more consistent stopping power that resists fade on spirited drives. From there, look at suspension tuning. Lowering springs or a well set up coilover kit can reduce body roll and tighten up the stance without ruining ride quality if you choose carefully. The E63 can feel a bit nose-heavy and prone to understeer, so stiffer anti-roll bars, upgraded dampers and fresh polyurethane bushes help it turn in sharper and feel more agile. Chassis braces and strut bars add stability through fast sweepers, making the car feel more planted and predictable. Done in stages, these handling mods transform the E63 AMG into a more responsive, fun and confidence-inspiring performance car without going overboard.

Frequently Asked Questions

What are the best first performance mods for a Mercedes E63 AMG?

For most E63 AMG models, a sensible starting point is an ECU remap or tuning box, paired with a high quality panel or intake filter and a freer flowing exhaust or downpipe setup. This combination usually gives a noticeable bump in horsepower and torque, with sharper throttle response and better mid range pull.

After that, many owners move on to uprated intercoolers, charge pipes and spark plugs to keep intake temps and combustion nice and stable. These supporting upgrades help the engine cope with the extra boost and make your tuning more consistent in different weather conditions.

How much power can I gain from an ECU remap on my E63 AMG?

On a stock Mercedes E63 AMG, a well written ECU remap can deliver strong gains in both horsepower and torque, especially on the twin turbo V8 models. You can expect a noticeable increase in straight line performance and a much more eager feel through the rev range.

The exact numbers depend on your specific engine code, fuel quality and what other performance parts you have fitted, such as intake, exhaust and intercooler upgrades. The key is going with a reputable tuner who understands AMG engines and can keep the map safe for UK fuel and daily driving.

Is tuning my E63 AMG reliable for daily use?

With sensible tuning and the right supporting mods, a mapped E63 AMG can stay perfectly usable and reliable for everyday driving. Keeping on top of servicing is vital, especially oil changes, spark plugs, ignition coils and quality engine oil that meets Mercedes spec.

We always recommend monitoring things like oil level, coolant condition and tyre wear a bit more closely once you start modifying. If you push for very high power figures, you should also look at upgraded cooling, transmission servicing and possibly uprated drivetrain components for long term peace of mind.

Do I need any supporting mods before going Stage 2 on my E63 AMG?

Yes, for a typical Stage 2 style setup on a Mercedes E63 AMG you should plan on a high flow intake or panel filter, a less restrictive exhaust system, sports cats or decat downpipes where legal, and improved intercooling. These parts help the engine breathe, manage heat and make the most of the ECU tune.

On higher mileage cars it is also wise to refresh spark plugs, coils and check the fuel system so you are not asking tired components to handle extra boost. Good tyres and brakes are just as important as power, so budget for performance pads, discs and quality rubber if you have not already upgraded them.

What wheel and tyre sizes work well on a tuned Mercedes E63 AMG?

The E63 AMG comes with fairly aggressive factory wheel and tyre sizes already, but many owners move to lightweight performance alloys to cut unsprung weight and sharpen steering. Common options are 19 or 20 inch rims, with a slightly wider rear tyre to help traction.

Exact fitment will depend on your chassis generation and whether you are running lowered suspension or coilovers. As a rule, stick to sensible offsets, use quality tyres and avoid stretching the sidewalls too much, especially if you want the car to cope with UK roads and wet weather without tramlining or rubbing.

Will an aftermarket exhaust make a big difference on my E63 AMG?

An aftermarket exhaust system on an E63 AMG usually brings two main benefits, improved sound and a small but useful performance gain. A freer flowing cat back or turbo back system can reduce back pressure, which helps the turbos spool more efficiently and supports any ECU tuning.

Resonator and silencer choices will affect how loud and refined the car is. Many owners go for a valved exhaust so they can have a deep, aggressive note when they want it, but still keep things civil for motorway cruising or early morning starts.

How much should I budget for tuning and mods on a Mercedes E63 AMG?

The cost of upgrading an E63 AMG varies a lot depending on how far you want to go. A basic ECU remap and intake upgrade can be relatively affordable and still transform how the car feels. Adding a performance exhaust, intercooler and other bolt on parts will raise the budget but also give you a more complete package.

If you are planning a full build with hybrid turbos, upgraded fuel system, coilovers, big brake kit and lightweight wheels, you should be realistic and budget several thousands of pounds. It is usually better to plan a clear upgrade path and buy proven performance parts once, rather than cutting corners and replacing items later.

Final Thoughts On The Mercedes E63 AMG

The Mercedes E63 AMG is already a serious bit of kit straight out of the box, with a powerhouse V8, brutal in-gear shove and that classic AMG soundtrack. It blends executive comfort with proper performance, which is why so many owners see it as the perfect base for tasteful tuning and motorsport-inspired upgrades. With smart choices, you can sharpen the edges without losing what makes the E63 such a great fast daily in the first place. On the performance side, the twin-turbo V8 responds very well to intake, exhaust and remap upgrades, giving stronger mid-range punch and better throttle response. One known weak spot is heat management, especially on hard road use or track days, so uprated intercoolers, cooling hardware and higher quality fluids are popular additions. The gearbox and driveline are usually solid if looked after, but aggressive torque increases benefit from careful mapping and, on higher power builds, supporting transmission upgrades for long term reliability. Chassis-wise, the stock air suspension can feel a bit soft and floaty when you really lean on the car, and body roll is not exactly “motorsport spec”. Performance coilovers or upgraded air setups, along with anti-roll bars and proper fast-road geometry, can completely change how tight and confidence-inspiring the E63 feels. Combine that with lighter alloys, stickier tyres and a subtle brake upgrade, and you have a big saloon that turns in far more keenly without ruining comfort. Styling tweaks finish the package, from de-chromed trim and carbon aero to more purposeful wheels that fill the arches properly. The key is matching power, handling and looks so the Mercedes E63 AMG feels balanced, dependable and still easy to live with every day. Build it with the right parts and a clear plan, and you end up with a seriously rapid, personal E63 that reflects your taste and the way you actually drive, not just numbers on a spec sheet.
