Search "Audi Q5 modified" and you get two kinds of results: show cars on air suspension that never see a grocery run, and forum threads where someone bought parts in the wrong order and is now pricing a new PCV valve at the dealer. Your Q5 deserves better. It is a family SUV first, so the best mods make it faster and tougher without making it annoying. Below are five example build recipes, each a starting template rather than a customer car, built from parts that actually fit the Q5 and SQ5. Most of them start in the same place, with the Titanium Intake V2 for the Q5 and SQ5 3.0T, because breathing is the cheapest place to begin.
First, Know Which Q5 You Are Modifying
Parts fitment on the Q5 depends on generation and engine, so check before you add to cart:
- ✅ B8 and B8.5 Q5 (2009-2017 US): 2.0T four-cylinder, 3.2 V6 and, from the 2013 model year, the 3.0T supercharged EA837 V6.
- ✅ 8R SQ5 (2014-2017 US): supercharged 3.0T EA837, the platform with the deepest parts catalog.
- ✅ B9 Q5 and SQ5 (2018 on): 2.0T four-cylinder in the Q5, turbocharged 3.0T EA839 in the SQ5.
The supercharged 3.0T cars get the most from these recipes. If yours is a 2.0T or 3.2, skip to the chassis, brakes and wheels recipe.
Why a Modified Q5 Needs a Plan
The 3.0T engine hides its weak spots in the valley under the supercharger: a plastic thermostat housing that cracks, a PCV valve diaphragm that tears, a water pump that weeps, all buried under a blower that takes hours to remove. Add boost first and you find those failures faster. The smart order is simple: fix the known failures, add airflow and ignition, then boost, then heat management and exhaust to match. Chassis parts slot in whenever the budget allows.
Recipe 1: The Reliability-First Daily
For the owner who wants a Q5 that stays out of the shop and feels tighter every day.
- ✅ Under Supercharger Kit for the B8.5 Q5 and SQ5 ($649.99): billet thermostat housing, aluminum heater pipe, Graf water pump, Hengst PCV valve, Elring gaskets and injector seals
- ✅ Billet PCV housing adapter ($74.99) to replace the fragile lower plastic section and allow PCV relocation
- ✅ Zeus ignition coil kit for the EA837 ($129.99)
- ✅ TruShift transmission mount upgrade ($19.99) for crisper shifts and less driveline slop
No tune required, and every part here fixes something the factory made out of plastic or soft rubber. Pay the labor once, skip the Audi Tax twice.
Recipe 2: The Stage 2 Sleeper SQ5
Stock looks, stock sound at cruise, noticeably more shove when you ask for it. Start with Recipe 1, then add:
- ✅ An ECU flash tune plus a transmission tune for the eight-speed
- ✅ TruDrive overdrive crank pulley ($249.99-$329.99), stainless hub with swappable 179mm to 207mm rings
- ✅ Titanium Intake V2 ($359.99) with heat shield and fuel line relocation kit
- ✅ Billet supercharger tensioner pulley ($64.99-$111.99) and a fresh belt
This is the classic single pulley setup. Our Audi SQ5 tune guide explains the stages in detail.
Recipe 3: The Dual Pulley Road Trip SUV
For the SQ5 owner who wants maximum boost but still needs the car to tow the family 500 miles in August. Build on Recipe 2, then add:
- ✅ A smaller supercharger pulley matched to your tune (dual pulley)
- ✅ GP Ice heat exchanger v2 ($449.99, currently pre-order) to fight heat soak
- ✅ High flow cats for the Q5 and SQ5 3.0T ($1,049.99-$1,299.99), rated to 950°C and made to order
- ✅ TruSport engine mounts ($299.99), void-free 65A rubber with a built-in emulator for active mounts, listed for 2008-2016
Why the cats? Past a basic single pulley setup, factory converters see heat and flow they were never designed for. Our high flow catalytic converter guide covers the details, and our heat exchanger upgrade guide explains the cooling side.
Recipe 4: Stop, Steer and Stance
Any B8 or B8.5 Q5, including the 2.0T and 3.2, can run this one. A heavy SUV with more power needs more brake before it needs more anything.
- ✅ Anker Street big brake kit ($1,849.99-$1,899.99): four-piston calipers from the B9 RS5 and 4M Q7, 380mm rotors, billet brackets and stainless lines
- ✅ Forged VF-06 wheels ($1,504.99-$2,794.99), fully forged 6061-T6, made to your exact vehicle in 19 to 24 inch sizes
- ✅ TruShift transmission mount for sharper response
Plan brakes and wheels together so the caliper clearance is confirmed before the wheels are machined. Our Audi wheel fitment guide walks through offset and clearance.
Recipe 5: The B9 SQ5 Starter
The 2018 and newer SQ5 is turbocharged, so pulleys and the 3.0T supercharger parts do not apply. Honest list of what we offer for it today:
- ✅ Zeus ignition coil kit for the EA839 ($199.99)
- ✅ 4 bar MAP sensors for the B9 EA839 ($99.99) for higher boost tunes
- ✅ TruShift transmission mount ($19.99), which also fits the B9 Q5 2.0T
Audi Q5 Modified Recipes Compared
Recipes 1 and 4 need no tune. Recipes 2 and 3 need a matched tune and the healthiest possible engine. Recipe 5 is for the turbo EA839 SQ5 only.

| 1. Reliability-first daily | 2013-2017 Q5 3.0T, SQ5 | No | Under supercharger kit, PCV adapter, coils, mount |
| 2. Stage 2 sleeper | SQ5, Q5 3.0T | Yes | Crank pulley, intake, tensioner |
| 3. Dual pulley road trip | SQ5, Q5 3.0T | Yes, custom recommended | Both pulleys, heat exchanger, high flow cats, engine mounts |
| 4. Stop, steer and stance | B8/B8.5 Q5 and SQ5 | No | Big brake kit, forged wheels, mount |
| 5. B9 SQ5 starter | 2018+ SQ5 EA839 | Only for MAP sensors | Coils, 4 bar MAP sensors, mount |

Buyer's Checklist Before You Modify
- ✅ Confirm engine code and model year before ordering anything
- ✅ Scan for codes and fix leaks before adding power
- ✅ Budget for a tune alongside any pulley or throttle work
- ✅ Check local emissions rules before changing cats
- ✅ Keep receipts and logs: they help resale and troubleshooting
Install Notes
The under supercharger kit is the big job: the blower comes off, so plan a full weekend at home or a day at a good independent shop. Intake, coils and the transmission mount are driveway work with hand tools. Pulleys need a crank holding tool and a new belt. Brakes and wheels are straightforward, but bleed the system properly and bed the pads in before towing or road trips.

Audi Q5 Modified FAQ
What is the best first mod for an Audi Q5 modified build?
For a 3.0T Q5 or SQ5, fix the known failure points first (PCV, thermostat housing, water pump, coils), then add an intake. For a 2.0T or 3.2 Q5, start with the transmission mount and brakes.
Are these real customer builds?
No. They are example recipes that show how our parts combine for different goals. Your ideal combination depends on your car, your tune and how you drive.
Does the Titanium Intake V2 fit the regular Q5?
It fits the B8 and B8.5 Q5 and SQ5 with the 3.0T supercharged engine. It does not fit the 2.0T or 3.2 V6.
Do I need a tune to modify my Q5?
Not for reliability parts, coils, mounts, brakes or wheels. Pulley changes should be paired with a tune, and larger airflow changes need one to deliver their gains.
Can I modify a 2018 or newer SQ5?
Yes. The B9 SQ5 uses the turbo EA839, so pulleys do not apply. Coils, 4 bar MAP sensors for higher boost tunes and the TruShift transmission mount are good starting points.
Will a big brake kit fit my Q5?
The Anker Street kit fits the B8 and B8.5 Q5 and SQ5. Check wheel clearance for the 380mm rotors before ordering new wheels.
How much does it cost to modify an Audi Q5?
It depends on the recipe. A reliability refresh starts with the under supercharger kit, while a dual pulley SQ5 with cooling and cats is a multi-thousand dollar project. Prices for each part are listed above.
Bottom Line on Your Audi Q5 Modified Build
An Audi Q5 modified the right way still does school runs and road trips, it just does them with more confidence. Fix the valley, add air and spark, then add boost with cooling and cats to match, and give it the brakes to stop it all. Start with the Titanium Intake V2 for the 3.0T Q5 and SQ5 and build from there.
