What are hte best plugs out there for a Naturally Aspirated3800 engine?

I saw these things at Auto Zone by Bosch.. they had 4 of those tips on them. Are they very good? Do they make a better spark? Are the yreally restricting hte spark?


What spark plug wires do I want?

 

Couldn't really help you much, I've kinda been wondering the same thing for my 3.9l.

Anyone hear anything about these pulstar plugs? Pulstar.com, I saw an ad in a magazine for them, they say they're more advanced than normal spark plugs, burn better and quicker, improve power, burn cleaner, blah blah blah. Supposedly guaranteed to do so and won't harm any engine.
What do you think?

 

walk into your trusted parts store, ask your favourite parts dude for plugs, and TA DA!!!

 

What ever you do dont buy the bosch plus 4s.They arnt good at all.I put them in my old truck and it ran like poo.Changed to ac delco platnums and ran perfect.I changed plugs in my other car at the same time with the plus 4s same thing as the truck.I would recomend ac delco platnum or champion double platnum.

 

has anyone changed their spark plugs? how do you get to those?

 

I'd just get regular old platinum delco stock plugs. Stock heat range. Should last 100k miles no problem.

Its all marketing hype- just get regular old stock plugs. If having 2+ electrods was so much more efficient and made more power with better gas mileage, GM would've done it from the factory.

Stock

Follow the plug wires, pull them off (one at a time), use a spark plug socket to remove the old plug- put the new one in, put the wire back on, and move to the next one.

 

sounds easy enough, thanks man

 

WHAT EVER YOU DO DONT PUT BOSCH IN YOUR CAR!
they are known to cause trouble in many american cars
get NGK IRIDIUM plugs, they work great, i picked mine up at Advanced Auto Parts

oh, and have fun changing your plugs[:@]

 

I just bought some bosch iridium fusion and so far so good! car starts up quicker and i notice better response, but so far i have just installed the front 3,i gave up on the back 3[:@] also dont forget the bosch wires, they will run you 50 dollars.
