Each kit pairs direct-replacement coil packs with matching iridium plugs for consistent combustion. Pair your fresh ignition setup with a performance tune for Acura or explore our broader lineup of ignition parts compatible with Acura.
What years and engine options do these TSX ignition kits cover?
Our inventory supports select applications of the 2004–2014 Acura TSX. We offer tailored coil and iridium plug kits for first-generation 2.4L 4-cylinder models (2004–2008), second-generation 2.4L models (2009–2014), and the second-generation 3.5L V6 (2010–2014).
Why replace coil packs and spark plugs at the same time?
As iridium spark plugs wear, their gap widens, forcing your ignition coils to draw extra energy to bridge the gap. Installing matched sets from our performance ignition selection prevents aged plugs from prematurely burning out fresh coils while ensuring balanced spark across all cylinders.
Will these kits clear P0300 through P0306 misfire codes?
Yes, if the diagnostic trouble codes are caused by failed coil boots, internal insulation breakdown, or fouled plugs. Replacing the complete set resolves single-cylinder faults (such as P0301 through P0304 on 2.4L engines, and up to P0306 on 3.5L V6 models) as well as random multiple misfire codes (P0300).
Are 2.4L 4-cylinder and 3.5L V6 TSX ignition coils interchangeable?
No. The 2.4L inline-four and the 3.5L V6 require distinct coil pack designs, resistance profiles, and physical quantities (four coils versus six coils). Always verify your exact engine displacement and model year before placing your order.
