NGKSpark Plug PFR8S8EG Laser Platinum 94460

If you have a performance vehicle, iridium spark plugs in my opinion are the best way to improve ignition, as they create a more efficient, stronger spark this will reduce knock, improve combustion, and the overall life of the engine in both naturally aspirated and forced induction variants. They don’t particularly increase horsepower or torque but you can tell the difference.NGK offer the best price for performance in my opinion

Perfect fit for my 2011 Audi S4 B8 also cheaper than anywhere else at the time
