3.4 Fuel Injector Upgrade

So I'm the process of upgrading my valve cover gaskets on my 2003 3.4 Tacoma.

As I was removing the Fuel injector connections I noticed one fuel injector had a small leak.

After a bit of research I noticed that Denso are being recommended for an upgrade from the Aisin fuel injectors that come standard.

So I'm looking online and found West Motors that sells a kit for $329.

Then I saw that AutoZone sells a set for $250.00

It seems like the AutoZone one is also a Denso rebuild injectors from a brand called GP Sorensen.

Any suggestions?

 

I also used these OEM injectors from the 3.0L 2JZ-GE (23250-46090 / DENSO 3320) with great results if you want a slight upgrade.

 

You could just replace the seals and filter. Or have them sent out and rebuilt.
