Fuel injectors?


I need to put new fuel injectors in my 97 tj 4.0.
Any suggestions for a good upgrade? I'm planning on going with Bosch. Not sure if I should get oem, or try the 4 hole. Is anybody on here running them and are they worth the extra money? Thanks for input.

I think most effect people feeling from switching to 4 hole injectors, is that their old injectors were fouled up. If you can get a good price on Neon injectors, then do it, it won't hurt.

I read that 12 holes exist. I HAD a website for them, but I can’t think of it now. The reading I did said it was all smoother idling when you upgraded from the 1 hole. Maybe I can dig around and find that website.

Plus an internet search will get you what you wan.


FYI: On a side note, don't do this on a 2006 Jeep Wrangler TJ. The 2006 4.0L has 'different' injectors than most other 4.0L jeeps.
I ended up going with the oem replacements from summit. And I have no complaints. The old jeep runs great.
