I'm getting ready to do my header/cat-back install and here's what I've got so far.

1)Jet-Hot coated Mac single cat headers
2)off-road pipe
3)02 simulators
4)Taylor OVC wires
5)Borla cat back (single cat)

While I'm at it I'm going to do the following but are the part#'s correct?

1)LT4 KM Part#16214681
2)Fuel Filter Part#25121293
3)Gm Manifold Gaskets Part#12550033
4)Front 02 sensors Part#25312184

Lastly, what plugs should I run? I was thinking of Delco plats or NGK TR55 Plats. What's the part # for the delco's?

Anything else that I need? I'm also going to have some high temp RTV sealant and will be using a nce lift at a GM dealership with the help of my brother, a GM mechanic!

Thanks and if there's anything I should know don't hesitate!

 

do not use bosch plat's, i have had hell with 2 sets, my friend has had good luck with the tr55's though, my delco plats with 75k on them we're doing really well, i wish i had'nt replaced them with ****ty bosch's
my .02

 

The delco is part #3 i believe.

Forget the GM gaskets, order some felpro. #1406

Also Tr55 are copper plugs, not plats.

 

i have bosch quad plats and theyre fine so far

 

keyword "Quad Plats" im sure they are good, mine normal plats are horrible, premature wear, and bad gas mpg due to plugs.....see other posts with search
