Injector Insulators

[HooahGST]

Ok. I have a set of Denso 550's. The stock insultors "looked" in pretty good shape. But they are plastic ( or really dry rotted rubber) and didnt fit the 550's without cracking. My question is: With the Denso 550's, will the Factory insultors fit, IF NEW? Because obviously they wont if used! If somebody can tell me if they are rubber (dry and old) or plastic, that could also help.
AND,
Where can i find them besided the dealership and online? The dealership is closed til monday!!!! I've called autozone and a few others and they are clueless.
thanks

They are supposed to be soft rubber but over time with the heat from the engine they turn plastic-like. As far as somewhere to get them the dealership and online is the only place i know of if autozone or advance doesn't have them. Good luck with ## search.

Thanks man.
That makes sense. I could see them fitting if they were rubber, nice and snug. I found a whole set from NAPA. 11.99 for all 3 seals needed. Thats cheaper than the online stores i found. Hope NAPA has them in stock tomorrow or else its to the dealership monday!
thanks again

11.99 for all 3 seals needed.

3?

I just received a set of the Viton seals from Fuel Injector Clinic-- they're supposed to work really well. Hopefully I can verify that pretty soon.

Well i guess one isnt a seal. But yeah 3. The o ring, the insulator, and the top rubber holder dealy thing that connects it with the fuel rail. 4 sets of 3 for 11.99. Hope its in stock!

Oh, OK-- I misunderstood. Sorry about that. I thought you meant one seal for each injector, for a total of 4. Remember to lube the top O-ring where it goes into the fuel rail, or it'll tear and leak.
