Question Questions about Spark Plugs, Plug wires, & Ignition Coil

Well I am wondering what spark plugs and spark plug wires do you all suggest?
(Brand? Style?(copper, platinum, iridium) Gapping?)

I always here about cars running better on certain plugs.

Also while I am here what ignition coil do you all suggest too?
Mine is the big brick style I think its called a Magnovox coil?
Is there a way to covert it the 3 separate coils?

Well thanks for help help!

Any help is greatly appreciated!

No particular brand preference but be sure whatever you get meets or exceeds oem standards.

Which model/engine do you have?.

it says l27 in his sig, thats the na s1 3800. you want at least platinum on a NA engine dont get crappy wires either they dont like that. i was running delphi wires for a while but the dont last anymore like most things it seems. personally i think its worth the money for msd wires and E3 plugs. not so much for the power but the smooth idle and its lasted alot longer than anything else ive tried.

The can of worms is officially open!

In all seriousness, most 3800'* shipped with iridium plugs from the factory. For stock performance (and up to 100,000 miles between changes), go with iridiums. Copper plugs are fine and cheaper, but they have about one-third of the shelf life due to the relative softness of the metal. Platinums also work, if you're not 'charged.

Only those people with modified engines need to worry about what material and heat range of plug to buy. Case in point, I ran copper plugs for a while and noticed no difference whatsoever. Having fresh wires and good coils matters more.

Just avoid Bosch plugs; they wear out very quickly in a waste-spark setup like ours, a design issue that Bosch themselves has noted.

Autozone has a deal on autolite sparkplugs. 3 bucks each and a rebate of 1.25 for each...

The first thing I do in all my NA 3800'* is slap in a new set of AC Delco iridium'* with a set of Bosch wires that have the life time warranty and write that off my maintenance check list for good.

A lot of us boosted guys run Autolite copper plugs. Cheap, dependable, and with many temperature variances for the different boost levels we run.

I change my plugs every year, so I run autolite coppers. Menards sells them for about $2.50 a pair. Can't beat the price. OEM life time plug wires and your set there. Stock OEM coils. There is no better coil, only worse coils. My engine is far from stock, and even though I have MSD coils in the picture, I removed them and went back to stock coils.
