High-voltage energy arcs to the cylinder head rather than jumping the plug gap. This causes multi-cylinder misfires, raw fuel dumping into the catalytic converters, and triggers a flashing CEL.

Upgraded internal copper windings deliver a stronger spark. The included iridium spark plugs utilize an ultra-fine wire center electrode that requires less voltage to fire while resisting gap erosion.

The factory coils suffer from severe thermal degradation due to their location directly atop the cylinder head, leading to micro-cracks in the internal epoxy housing. This structural failure results in voltage leakage, erratic idle, high-RPM misfires, and delayed throttle response. Furthermore, standard OEM spark plugs experience rapid gap erosion under high cylinder pressures, compromising the combustion event and significantly reducing both power output and engine efficiency.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive ignition overhaul addresses the EA888's thermal shortcomings by utilizing premium, high-dielectric epoxy resin in the upgraded ignition coils to withstand extreme heat cycling and prevent voltage breakdown.

Paired with six matched, pre-gapped spark plugs with corrosion-resistant terminal studs, this kit delivers consistent spark energy across all six cylinders and eliminates voltage drop without demanding wiring modifications.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100% style=\" border-collapse: collapse border: solid font-size: min-width:\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1998-2001 Audi A4, A6\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eAHA \/ ATQ (EA835)\u003c\/strong\u003e \/ \u003cstrong\u003eB5, C5\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e190 hp \/ 207 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eUF256\u003c\/strong\u003e, \u003cstrong\u003eC1171\u003c\/strong\u003e, \u003cstrong\u003eC-684\u003c\/strong\u003e, \u003cstrong\u003eIC381\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1998-2001 Audi A4 2.8L V6 (Chassis: \u003cstrong\u003eB5\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e1998-2001 Audi A4 Quattro 2.8L V6 (Chassis: \u003cstrong\u003eB5\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e1998-2001 Audi A6 2.8L V6 (Chassis: \u003cstrong\u003eC5\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e1998-2001 Audi A6 Quattro 2.8L V6 (Chassis: \u003cstrong\u003eC5\u003c\/strong\u003e)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the B5 and C5 A4, A6?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1998-2001 Audi A4 and A6 equipped with the 2.8L 30V \u003cstrong\u003eAHA\u003c\/strong\u003e and \u003cstrong\u003eATQ\u003c\/strong\u003e engine codes.\u003c\/p\u003e\n\n\u003ch4\u003eDoes this kit include spark plug wires?\u003c\/h4\u003e\n\u003cp\u003eNo, high-tension spark plug leads are sold separately; this kit contains the single waste-spark coil pack and six spark plugs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Audi Precision Benchmark\u003c\/h3\u003e\n\u003cp\u003eEuropean Motronic engine management systems depend on exact resistance values to maintain clean emission parameters and accurate misfire detection.
