For 2005-2007 Land Rover LR3, stable engine operation depends on 6H2E-120-29AA ignition coil’s stable boost. Mounted above the cylinder head, it converts low-voltage from the battery to high-voltage to precisely ignite the air-fuel mixture in the cylinder. OEM: 6H2E-120-29AA; designed for 4-cylinder versions; direct replacement with no modification required. Replacement difficulty medium; estimated labor 1–1.5 hours; avoid damaging high-voltage harness during removal. If you experience acceleration hesitation, idle vibration, MIL, or higher fuel consumption, it often signals aging ignition coil.
