The 5400 is the triple oversize kit , for the 4.6 or 5.4 , that has had a repair that failed , as in helicoil .
I have found that kit on amazon , 508.00.
I have a 96 f150 with tbe 4.6 , that has had 1 plug repaired and failed .
Thanks for your reply .
I have a repair to a previous spark plug repair , hole now oversize .
I would rent andnpay for shipping both ways , and replacment inserts if some one here has this specic kit .
Thanks

In all these years , I may have had to replace , a handful of coils .
Mostly because some one wanted them replaced , or very few , that actually failed.
Usually boots and springs , fixes a misfire from ignition .
Never been a Hunter ...keep trying .
