Iridium Plugs for TFSI Engines
The Q7's 2.0 TFSI / 3.0 TFSI / 55 TFSI V6 Quattro engine requires iridium spark plugs — these cost more than copper or platinum plugs but last significantly longer (60,000 km vs 20,000 km). Using cheaper plugs in an Audi TFSI direct-injection turbo engine causes rough idle, misfires, and can trigger coil pack damage which is expensive to fix. Always replace all plugs as a full set and inspect ignition coils while the engine cover is off. At 4M Car Care iridium plug replacement on the Q7 is scheduled at 60,000 km intervals.
