Audi A4 Spark Plug Replacement Cost: What You Will Actually Pay
An Audi A4 has only four plugs, yet it costs more than double a four-cylinder Camry to service. The premium is not plug count; it is the OEM parts, the higher shop labor rate, and a service interval less than half as long. Here is exactly what the 2.0 TFSI A4 costs, the plug it actually takes, and how it stacks up against a BMW 3 Series.
Quick Answer: Audi A4 2.0 TFSI
Independent shop pricing. Audi dealerships run 25-40% higher.
Why an A4 Costs More Than a Camry for the Same Four Plugs
A four-cylinder Camry is $100 to $180. An A4 with the same number of plugs is $300 to $500. Three things drive that gap, and none of them is the number of cylinders.
OEM plug cost
The 2.0 TFSI specifies NGK PFR7S8EG plugs at roughly $15 to $25 each, versus $8 to $12 for a Toyota plug. Four of them is $60 to $100 in parts before labor, and Audi dealers charge more for the boxed OEM part.
Labor rate and access
Audi dealer labor runs $160 to $220 per hour, and even at an independent the engine cover and intake plumbing have to come off to clear the coil packs. That turns a 30-minute Camry job into a 1 to 1.5 hour job at a higher hourly rate.
Shorter interval
Audi's interval is roughly 40,000 miles, not the 100,000 of a Japanese car on iridium. Over 120,000 miles you pay for the A4 job three times and the Camry job once. The lifetime gap is much larger than any single quote.
The Plug It Actually Takes: NGK PFR7S8EG, Not Iridium
The single most-mislabeled fact about the A4 is the plug. The 2.0 TFSI (EA888) specifies NGK PFR7S8EG, part number 1675. These are NGK Laser Platinum plugs, not iridium, even though plenty of listings call them iridium. They ship pre-gapped to 0.032 inch, so you do not gap them yourself. The same plug runs across the VW/Audi 2.0T family, including the A5, Q5, and the VW GTI and Golf, so it is widely available.
Buy the genuine NGK part. The 2.0 TFSI is a direct-injection turbo engine that is sensitive to plug heat range and gap, and a cheaper wrong-spec plug can cause misfires under boost. The plug is the one place not to economize on this car.
Cost by Audi A4 Generation
The four-cylinder A4 is consistent across generations. The big jump is the S4, where a supercharged V6 with the blower in the valley makes the rear plugs a real job.
| Generation | Engine | OEM Plug | Shop Total | Notes |
|---|---|---|---|---|
| B8 (2009-2016) | 2.0 TFSI (EA888 Gen 2/3) | NGK PFR7S8EG (Laser Platinum) | $300 - $480 | Engine cover and intake plumbing come off to reach the coils. First plug change often listed at 35k, then ~40k. |
| B9 (2017-2024) | 2.0 TFSI (EA888 Gen 3B) | NGK PFR7S8EG (Laser Platinum) | $320 - $500 | Same four-plug layout. 2019+ schedule lists ~40k miles or 6 years. |
| B8/B9 S4 (3.0 TFSI V6) | 3.0 TFSI supercharged V6 | OEM platinum/iridium (6 plugs) | $400 - $700 | Supercharger sits in the V, so reaching the rear plugs is far more involved than the 4-cylinder. |

A4 vs Other European Compacts
The A4 sits in the middle of the European-premium pack. A VW GTI uses the exact same engine and plug for less labor; a BMW 3 Series is comparable money but on a longer interval.
| Vehicle | Engine | Interval | Shop Total |
|---|---|---|---|
| Audi A4 (2.0 TFSI) | EA888 I4 - NGK PFR7S8EG | ~40,000 mi | $300 - $500 |
| VW GTI / Golf (2.0T) | EA888 I4 - same NGK plug | ~40,000 mi | $220 - $400 |
| BMW 3 Series (N20/B48) | Turbo I4 - NGK/Bosch | ~60,000 mi | $300 - $500 |
The GTI is cheaper for the identical engine and plug because its labor times are shorter and its parts come without the Audi badge markup. See the full cost-by-car table for non-European vehicles.
Doing It Yourself
The 2.0 TFSI A4 is a moderate DIY job, not a beginner one. There is no exotic teardown, but you are working under a coil pack and an intake on a turbo engine where torque and the right plug matter. Done yourself, you keep the $150 to $280 in labor.
Pull the cover and coils
Remove the plastic engine cover, unclip the coil pack harness, and lift the four coils. Some years need the intake plumbing loosened to clear them. Label nothing; the coils are interchangeable but check for damage as you go.
Use the right socket
A thin-wall 14mm spark plug socket with a rubber retainer and a long extension reaches the recessed plug wells. A magnet helps you avoid dropping a plug into the head.
Torque, do not guess
The plugs thread into an aluminum head and ship pre-gapped to 0.032 inch. Torque to the spec in your manual with a torque wrench. Over-tightening strips the head; under-tightening lets combustion gases past the seat.
Genuine NGK only
Buy the NGK PFR7S8EG (1675). A wrong heat-range or off-brand plug can misfire under boost on this direct-injection turbo. It is the one part to buy genuine.

Common Questions
How much does an Audi A4 spark plug replacement cost?
An A4 2.0 TFSI runs $300 to $500 at an independent shop: $60 to $120 in parts for four OEM NGK plugs and $150 to $280 in labor because the cover and intake plumbing come off to clear the coils. An Audi dealer runs 25 to 40 percent higher. There are only four plugs, so the premium over a Japanese sedan is the parts and labor rate, not plug count.
What spark plugs does the Audi A4 2.0 TFSI use?
The 2.0 TFSI (EA888) A4 specifies NGK PFR7S8EG, part number 1675. They are NGK Laser Platinum plugs, not iridium despite frequent mislabeling, and ship pre-gapped to 0.032 inch at about $15 to $25 each. The same plug is used across the VW/Audi 2.0T family including the A5, Q5, and VW GTI/Golf.
How often should Audi A4 spark plugs be replaced?
Audi's interval for the 2.0 TFSI A4 is roughly 40,000 miles, with the first change on older B8 cars often listed at 35,000. That is well short of the 100,000-mile interval common on Japanese iridium-equipped cars, so an A4 owner pays for plugs more than twice as often. Confirm against your owner's manual.
Is the Audi A4 spark plug job DIY-friendly?
It is a moderate job. An experienced DIYer can do it in 1 to 1.5 hours and save $150 to $280 in labor by removing the cover, unclipping the coils, and swapping plugs with a thin-wall 14mm socket and torque wrench. The plugs thread into aluminum, so torque to spec. It is not a first-time-ever job.
