Best place to buy quality OEM injectors?

One of my J-SPEC tII injectors are cracked. Going to replace all four, and checker has some for 50 bucks each.. i've been looking for denso injectors but cant find em'.

Also, the injectors on my j-spec were red, i heard they were supposed to be purple??

Are buying remanufactured injectors a good idea?

Assuming your car is an 87.5-88, then you want the purple ones. Either way, reds are only for NAs, so they definately aren't the right ones.
As for injectors, I assume rebuilt injectors would be fine. You can actually buy used injectors for cheap in the f/s section of the forum, too.

The injectors have red tops, but read the purple part number. Being 195500-1370.. hmm.

found a place to buy all four injectors for 200 bucks. Go for it? Or does the term "you get what you pay for" apply especially to injectors?

when in doubt, go buy some reman ones. if you need the peice of mind, then the extra money will be worth it. Or otherwise, I would say its fine.

If it were me I'd get used ones then send them of to get cleaned and flowbenched, but reman ones should be fine. I see no reason at all to ever by new OEM injectors.

I thought that the 88 NA FC primaries flowed 550cc and the secondaries 460cc, while the TII was 550cc for both. are there any differences btwn the NA primaries and TII injectors, besides plug color/shape?

I bought two remanufactured Denso 550cc (primaries) and two Denso 720cc (secondaries) injectors for $282.90 shipped from TLF Performance Parts on Ebay. The shipping was extremely quick.
