Need new spark plugs...

[Max]

Hell no but it keeps the tb cleaner. I finally installed that spacer I've had laying around for almost a year today so I get to install some TR6s gapped to .035 this weekend

I did that to my 88 5.0 they had that same deal with pre heating the air. when you clean the trottle body you took it off right? I was going to do this when I get my CAI.

not to hijack the thread but it is on topic at least. My newly used purchase has 115K. previous owener as some time installed autolight wires. havent pulled a plug yet to see what they are. Think I should put Delco's back on it?

nice, thanks man!

i think the egr valve and where the tube mounts to the intake is what makes these tb's and manifolds get so gunked up

Why do you say that?

 

[Max]

Egr enters after the tb but that is all the more reason to get some longtubes and delete that shit.

Anybody have recommendations on who to go with for the Fuel Filter?

 

[gdddup]

i prefer the ac delco pf652 but you can also use fram g3727

So, I just looked in my Haynes Repair Manual at what spark plugs to get and it says for my 2002 that it requires "NGK PZTR-5A15 or equivalent". anyone know if there is any difference between those and the AC-Delco 41-110?

Just go to the parts store and get some ngk TR-5 plugs part # 2238.

So 41-100 is the new AC Delco part # that replaced #41-985? I got 95k on my 03 Tahoe, would wires be a good idea as well i guess?

i change my wires everytime i change my plugs because the wires r a pain in the ass to get off in one piece ecspecailly if they've been on there awhile. its easier to just grab the old wires with some vice grips r channel locks and pull. the spark plug clip in the plug wire usually pulls out when doing this making them useless but its much easier and wires arent that expensive.

On my Tahoe the air box says to gap plugs at .060 inches... So if you're doing .035 you're about halfway there. Thats unless you know something that I dont.

Your airbox is from 2002, they changed the specs because you're missing out on a little power and fuel economy by gapping them so damn wide. Additionally, I'm gapping my colder heat range plugs tighter (stock is recommended .040) due to the nitrous plate I have on my truck...but you should have known that if you blew your engine due to "way too much nitrous"
