We have designed this kit to fit Mazda Speed 3 6 2.3L DOHC fitted with E7T20171 GDI injectors. Included are the large top seals and our all-metal, free-flowing filter baskets. This kit will refurbish 4 injectors.
These filters are an upgrade of the originally fitted ones because they are resistant to being dissolved by the additives found in today's fuels and are completely free-flowing. They won't break down as the plastic-meshed ones do in most high pressure injectors so you won't have to worry about particles of these being pushed into the pintle shafts, reducing or blocking your flow rates.
The original split spacers need to be retained.
Contents
Kit 200 for 4 injectors contains:
4 x Top Viton seals
4 x All-metal filter baskets
Terms

⚠️ Petrol Compatibility & Injector Handling Notice
Petrol Only: Strictly for petrol engines, not diesel. Check compatibility before buying.
Delicate Mechanisms: Injectors—especially historic hose injectors—are fragile. Some components cannot be removed, replaced, or obtained anywhere. Check our kits before dismantling your own parts; some items are not available aftermarket. Do not force components loose or strip your injectors down until you know what we can replace, or the injector may need replacing.
Expert Fitment Advised: We strongly advise using a competent professional for installation to avoid common issues like over-tightening hose clamps or damaging pintle needles. If you are unsure about dismantling, fitting or refitting an injector, seek advice from a competent professional before proceeding.
Lubrication: The only lubricant we recommend is a light smear of clean engine oil, wiped almost completely off before fitting.
