Fuel Injector Seal Repair Kit for Subaru WRX STI Imprezza O-RIngs Filters Denso

Description

Fuel injector service - seal kit for 2005 & up Subaru WRX & Imprezza and 2007 and newer STI’s. Kit is designed for Denso Top Feed injectors as shown in picture. Kit includes the
OEM style lower cushion ring seal
instead of a generic type seal which is included in many other inferior service kits. Kit also includes pintle caps. We see many of these injectors without pintle caps and this is likely due to the pintle cap becoming brittle and cracked with age causing it to fall off the injector. You don’t have to use a pintle cap, but it is recommended. Pintle caps are used to try to reduce the deposits on the tip of the injector. When an engine is shut down some of the inlet valves will naturally be left open. This allows heat inside the cylinder to rise past the intake valve to the injector area. The heat begins to bake the residue of the fuel onto the pintle. This could lead to a build up over time which causes poor fuel spray, poor driveability and incorrect fuel mixtures. Micro basket filters also included. Upper o-ring retainers included and electrical connector plug seals included (see pictures). This kit will service four (4) injectors and
we also include extra parts
in case you have a mishap. We include one extra: lower seal, upper o-ring, filter basket, upper o'ring retainer, pintle cap & connector seal. Free shipping within the USA. Shipping cost to Canada is .00. Shipping to all other countries = .50. Paypal accepted. (
