Last weekend, I have attempted to change spark plugs on '05 AP2, 110K miles. I could not get them out easily, so sprayed some PB Blaster and left overnight.
After pulling out the ignition coils the next day, I realized that 3 of the 4 bushings separated from the coil. It must have been the PB Blaster that ate away the glue that was holding them.

Can I superglue them back and reuse, or is it too risky, considering they could get stuck on the spark plug end?
If I need to buy new ones, which brand?

 

At 110k, I'd replace them if they are falling apart. Denso are the OEM's, they are not cheap.

 

Just off-hand, I would not use super glue. Does there appear to be any damage to the rest of each coil pack?

 

No other damage that I can see.

 

Just replace them. if you have Prime, buy here.

 

You could try to glue it with heat-resistent Silicone = Engine sealant.
Or buy replacements...

 

The big question is, what happens if whatever glue you put causes them to fail. The caps look about the right height that they'll stick on top of your spark plugs, so it'll be a PITA (although not impossible) to fish them out.

I'd personally buy new ones. Some Autozones have "Made in Japan/Denso" coil packs for MY00-05 for $58.99 branded as Denso (obviously) or for $48.99 branded as Duralast (but look for the made in Japan/Denso sticker -- it's a must -- not all of them have it) that are exactly the same. FYI.

Or just Amazon it per the other guy.

 

Get K series coils.
