EurosportZ34 Posted January 16, 2004 Report Share Posted January 16, 2004 Does anyone know of some spark plugs and wires that add some performance? I'm thinking of going with AC Delco, but is there something out there that is better but also not too harsh on the cash flow?? Quote Link to comment Share on other sites More sharing options...
gp90se Posted January 16, 2004 Report Share Posted January 16, 2004 Which motor? what type of gas do you run and how hard do you run your motor? -Jeff Quote Link to comment Share on other sites More sharing options...
EurosportZ34 Posted January 16, 2004 Author Report Share Posted January 16, 2004 Sorry... It's for my 3.4, which I run Mid-grade gas (89oct). And I would guess I run it normal, I don't do too much yet, other then for my daily driver. But I want to make it fast enuf (when I'm done) to beat a stock 3.4 and motors with similar HP.

gp90se Posted January 16, 2004 Report Share Posted January 16, 2004 Id run either rapidfire or (much more $) denso iritium plugs. I dont like platinum, they wear out quickly. For wires, It it isnt delco, it dont go on my cars, unless there like 9mm. -Jeff Quote Link to comment Share on other sites More sharing options...

EurosportZ34 Posted February 12, 2004 Author Report Share Posted February 12, 2004 UPDATE: Ok, I finally checked with the auto parts places around my area and none of them can order AC Delco RapidFire sparkplugs for my 3.4L, they said there suppliers won't allow them to. Also they said that MSD Ignition doesn't make a wire set for the 3.4L. Are these peeps on crack or what's up with these plugs and wires?

cutlsp Posted February 12, 2004 Report Share Posted February 12, 2004 i like the split fire spark plugs they have lasted in my dad's delta 88 for about 5 years and it still runs like they were just put in :shock: i say go with split fire spark plugs they seem a lot better then the rapid fire spark plugs. as for wires you gotta look only for them. also i put some in my 2.8 and its running a lot stronger then it did a bout a year ago and its still running like i just put them in Quote Link to comment Share on other sites More sharing options...
DOHCRagtopguy Posted February 12, 2004 Report Share Posted February 12, 2004 That is strange. Why don't you use the stock Delco wires and Rapidfires and order them thru GM Parts Direct? That's what I did and the cars run great! Around here, Advance Auto Parts and Pep Boys all carry AC Rapidfires, maybe the help up there IS on crack!

grandprix104 Posted February 12, 2004 Report Share Posted February 12, 2004 nobody can order delco cause they stopped supplying anone but GM service dpts. you might try NGK v powers, Splitfire, bosh plats or doublePlats, delco is also good wires - id go with borg warner or MSD Quote Link to comment Share on other sites More sharing options...
GrandPrix34 Posted February 12, 2004 Report Share Posted February 12, 2004 i have a set of BOSCH wires that leak current! :-D Try either Magnecor, AC Delco's or custom make yours from MSD bulk wire. For plugs try http://www.rockauto.com and search for you car and spark plugs...they have the NGK G Power platinum (???) NGK V Power and the AC Delco Rapidfires Also, rsmracing.com has AC Delco wires for about $49.99 and the AC delco plugs for about 4 buxs each...check it out: http://www.rsmracing.com DIS Ignition System - Longer and hotter spark for increased performance and better fuel economy. Individual MSD performance coils ($49.99), AC Delco performance wires ($59.99) and Rapidfire and Rapidfire Platinum plugs also available Quote Link to comment Share on other sites More sharing options...
Zoomina34 Posted February 13, 2004 Report Share Posted February 13, 2004 Ive also been having trouble finding Rapidfires. one place told me they were discontinued and a couple others said they dont stock them and cant order them. When you say Rapidfire 8's , is the 8 the part number or the heat range? Also does anyone know thread size, tapered or not? If i cant find them i think i'll try those V Powers.

EurosportZ34 Posted February 14, 2004 Author Report Share Posted February 14, 2004 I just bought some AC Delco RapidFire spark plugs from a Pontiac dealership and bought some MSD Ignition 8.5mm Super Conductor spark plug wires from Autozone. They aren't a custoem fit :? but I'm going to have to fit them to my car. Thanks for all the info guys, I'll let you know when I'm all complete.

EurosportZ34 Posted February 24, 2004 Author Report Share Posted February 24, 2004 Alright, well I got the spark plugs in but the MSD wires will not work at all they are too small. I called AC Delco about getting some custom 8mm wires which might be an option, but I'm now also thinking about Magnecor wires. :? Quote Link to comment Share on other sites More sharing options...
optimusprime Posted February 24, 2004 Report Share Posted February 24, 2004 I put a set of Crane Firewires on my Buick and have been pretty happy with them. I'd rather have a set-of plug wires that I put together myself then a set of pre cut wires. They never seem to get the length right. I've also hear that Taylor wires where pretty good too. I'm not too sure if they make a boot for the DOHC though. Quote Link to comment Share on other sites More sharing options...
EurosportZ34 Posted February 24, 2004 Author Report Share Posted February 24, 2004 The boot is too small compared to the stock boot. Anyways I just ordered some 8.5mm Mangecor wires. I can't wait until them come in!! Quote Link to comment Share on other sites More sharing options...
EurosportZ34 Posted February 24, 2004 Author Report Share Posted February 24, 2004 The boot at the end of the wire was too small Quote Link to comment Share on other sites More sharing options...
joey b Posted February 26, 2004 Report Share Posted February 26, 2004 I see you bought rapid fire #12's. Why not 8's? Quote Link to comment Share on other sites More sharing options...
EurosportZ34 Posted February 26, 2004 Author Report Share Posted February 26, 2004 Because the 8s weren't available and the 12s were. Quote Link to comment Share on other sites More sharing options...
93CutlassSupreme Posted March 2, 2004 Report Share Posted March 2, 2004 what number rapidfire do you use with a 93 3.1? my owners manual only lists the standard plug number, acdelco.com lists rapidfire #6 as being the right plug, but someone here was refering to rapidfires #8 as being the right plug what number is it?

93CutlassSupreme Posted March 3, 2004 Report Share Posted March 3, 2004 yeah thanks you're right #6 is the right number i checked at the auto parts store Quote Link to comment Share on other sites More sharing options...
