Honda/Acura K ('01-'11), S2000 ('06-'09) Fuel Injector Clinic Injector Set: 4 x 1650cc Saturated / High Impedance Ball & Seat Injectors. Utilizing the latest injector technology and featuring state of the art matching with Data Match Technology. Includes PGTJETR4Q or add Plug &Play adaptors PADPJtoH4.

Fuel Injector Clinic’s 1650cc/min high impedance injector is the largest high impedance injector compatible with all race fuels and has excellent idle performance in street driven cars while still providing enough fuel to support higher horsepower output on both E85 and gasoline. 

The 1650cc high impedance injector can be used with any fuel type based on the stainless alloy valve construction. It is compatible with pump gasoline, E85, Q16, VP Import, FTW and other MTBE oxygenated race fuels!

This injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered and the results are provided on the  Data Match Sheet providing the most complete flow matching and latency value information available in the industry today. 

Fuel Injector Clinic injectors are flow tested and rated at 43.5psi (3Bar) at 120ºF (49°C) fuel temperature using 93 Octane, 10% E pump gasoline.

Superior short pulse width control and state of the art matching make these injectors easy to tune and provide great drivability.

Fuel Injector Clinic injectors are set up to and include all o-rings needed to fit the factory application for the listed vehicle. If you are using aftermarket or other unusual setups please contact us prior to placing your order to make sure you receive injectors that fit properly.

Every injector is covered against failure caused by defects in original manufacture by our lifetime warranty

This injector set contains high impedance injectors matched to the saturated injector signal generated by this vehicle’s OEM ECU, OR is suitable for use with an aftermarket ECU made or set up for high impedance injectors.

This set of injectors requires you to change the injector plug on the wiring harness in your car. This can be done by soldering in the pigtails (included with purchase) to replace the plugs currently on your harness, or you can choose to purchase the optional plug-n-play adaptors which will convert from the type of plugs on these injectors to the plugs on your harness without any need for cutting or soldering.

This plug conversion is made necessary because FIC always chooses to provide brand new, unused injectors for its performance applications. We do not believe that increasing the chance of a failure due to using remanufactured or core program based injectors is ever warranted.

Very good product
Size: Medium, Color: (001) Black / Black / Pitch Gray
I purchased these to wear inside lowcut slip on casual shoes, I don't particularly like to not wear socks in my shoes for hygienic reasons. Prior to purchasing these socks, all I could find were those made of very light beige hosiery type material , and my slip on shoes would slide around a bit. These are light weight and breathable athletic type material, with a very good gripper strip at the heel. One pair of my slip on casual shoes have a particularly lower cut in the toe area, but the shoe is black and I chose the black color and though I see a hint of the sock there, it matches and does not detract from the look of the casual solid black shoe

They stay out! No more sock wads!
Size: Medium, Color: (100) White / White / Mod Gray
Best no show socks ever made!!!!! I've been struggling for 2 years to find ones that actually stay on your foot, even other national brands, and I just became content wearing my sneakers without socks. They ALWAYS slid down into my show & I ended up walking on a wad of sock until I could fix it...or usually just took them off after a couple of tries. Enter Under Armor!!! They a mid weight, but not very thick & still breathable. They work too by actually staying on your foot! Not once have they slid down into my show!! Very comfortable but they could be a little more affordable.

Ive tried so many no show socks but I love these. This is the 3rd set I've bought. They never slip off and the material is thin and breathable. Perfect for working out.

True no-show socks that don’t slide down!
Size: Medium, Color: (100) White / White / Mod Gray, Size: Medium, Color: (100) White / White / Mod Gray
This is the first pair of no-show socks I’ve tried that actually don’t slide down into my shoes. Trust me… I have tried lots of different pairs and this is the one! They fit perfectly. They’re not too thick and they’re obviously durable because I wash them after each wear, so daily.

Great fit but expensive

These are really great socks. I love them, but they are definitely pricey.
