4 banger? If so read back, OP did this for a V6. Hose widths and sizing is different for some of the parts. It's discussed in the preceeding pages the differences.
no i have the j30a1 v6..... and aparently the 1/4" is for the j30..... it says under the picture of the parts "4cyl- Needs 5/16 brass splice
along with 5/16 vac. caps" ....... so im woundering what the correct size is my my model year of the j30 because the 01 and 02 have diffrent spark plug set ups then the 98-00, dont they ??? and im in a 01......
