Mishimoto 2011+ Subaru WRX / STI Ignition Coil Set of 4

The basic requirements for a properly running engine are fuel, air, compression, and spark. Before cranking up the boost in your flat four, it is wise to ensure all maintenance is up to date and these processes are performing as intended. Weak spark from your ignition system can result in misfiring under high load driving, and spark blow-out under high boost, which is bad for performance. Mishimoto is proud to launch our new lineup of ignition coils, aimed at providing a high-quality replacement that can bring your vehicle up to Stage 0 before moving on to horsepower adding modifications. Our ignition coils are designed and tested to meet or exceed OEM Subaru performance standards and are available as a single coil or in sets of four. Once installed with a set of new spark plugs, one can expect a refreshed ignition system with improved engine startup, a smoother idle, and restored performance from your EJ. The primary frame of our coils is constructed from extremely robust phenolic resin, ensuring optimal longevity in high temperature environments. The precision lower boot provides a barrier against moisture entry into the plug well, eliminating chances for spark plug contamination. In addition, our coils are pre-lubricated with dielectric grease to prevent corrosion and ensure an optimal connection between the spark plug and coil. Mishimoto ignition coils are an ideal replacement for worn or defective factory coils. As with all our products, these ignition coils include our signature Mishimoto Lifetime Warranty.This Part Fits: Year Make Model Submodel 2011-2013 Subaru Forester X 2011-2013 Subaru Forester X Limited 2011-2013 Subaru Forester X Premium 2011-2013 Subaru Forester X Touring 2011-2013 Subaru Forester XT Premium 2011-2013 Subaru Forester XT Touring 2011 Subaru Impreza 2.5i 2011 Subaru Impreza 2.5i Premium 2011 Subaru Impreza Outback Sport 2011-2014 Subaru Impreza WRX 2011-2014 Subaru Impreza WRX Limited 2011-2014 Subaru Impreza WRX Premium 2011-2014 Subaru Impreza WRX STI 2011-2014 Subaru Impreza WRX STI Limited 2010-2012 Subaru Legacy 2.5GT 2010-2012 Subaru Legacy 2.5i 2010-2012 Subaru Legacy 2.5i Limited 2010-2012 Subaru Legacy 2.5i Premium 2010-2012 Subaru Outback 2.5i 2010-2012 Subaru Outback 2.5i Limited 2010-2012 Subaru Outback 2.5i Premium 2015-2020 Subaru WRX STI Base 2015 Subaru WRX STI Launch Edition 2015-2020 Subaru WRX STI Limited 2019 Subaru WRX STI S209 2016 Subaru WRX STI Series.HyperBlue 2018 Subaru WRX STI Type RA
