need opinions on spark plugs

[o4aveohb]

I just bought a set of Iridiums as well, im not sure if I want to wait until I can get new wires or if I should just go ahead and plug them in.

TAKES 20 minutes to do the plugs. change them its easy,, then go back and change your wires when you get them, that'll take 10 minutes.

Well i was checking out what the plugs looked like and i thought it was time to change them. here is a photo of just one of my plugs




Changed out the Wires Too. the Wires lookd like they where done and probley the OG Wires from 86,000 miles.

I had used DENSO Iridum IK20 and NGK Iridium BKR6iex11.

Both are good. No significant difference. Used them for at least 40,000 km each.

From what I have personally seen, the Pulstar plugs are ****. Here is a story from a local. His car is a cammed 02 Vette with a couple more mods.

Well for those that remember. I convinced the makers of pulstar plugs to send me a free set. For my car that comes to $200.00 worth of plugs.. These plugs were suppose to crank up the spark.. increase compression and power..

I worked out a time to borrow the dyno at dynosport to run some test. What i had in my car going to the dyno were all Acdelco uraniums with about 4,000 miles on them.. THey are 100,000 mle plugs so i figured they were still good... at this point its giving the pulstars the advantage.. Well after doing some averaging.. it was concluded the pulstars increased power by 1hp and lost 1tq at the wheels over my used Acdelcos. I left them in to see if it would increase fuel econ. At first it seemed like i gained a couple mpg in town.. but after a few weeks that tappered off. I assume the difference wasn't the plugs but possibly gas/driving/enviroment and all the lil maintance i did before going like cleaning my maf.

Long story short.. they dont' work atleast not as advertised.. All the cars they test are stock... My car is no where near stock.. however considering the method they are suppose to work... there should be equal improvement on my car over a stock...


Welll it gets better. My car started acting up after the first snow storm... I kept thinking it was probably my 02's. They needed to be replaced but this didn't feel like 02s. although the rich smell and hte o2 codes said otherwise..

Well to get to my o2's i have to lower my headers. NOT an easy task... because of the way they drop i have to remove my sparkplugs... which means remove the pulstars... the first one came out just fine... looked just fine (color of the plug thats in the head) but that was the last one that came out that way.. every other one came out breaking... the ceramic coating that is... one was broken before i even put the socket over it. i had a hard time getting my socket over it.. because of the ceramic piieces laying underneither the plug on the head... so after strugglling for about 5 mins with it i finally go it off and it came out in peices.. just the top half everything inside the head was ok.. but this was obviously my problem.. So long story short they dont' work and are piles of ****.

I installed the Pulsestar plugs and they are awesome! I get better gas mpg and more power comes with a 5 yr guarantee!

Are you serious?

Whats the mpg difference?

A 5 year warranty seems kinda pointless if you're supposed to change them at 50,000km. I know it makes sense if you only drive your car 10,000km a year but that seems unrealistic.

I been getting help from this forum since i bought my AVEO a year ago. I have to thank all of you for the advise and information you guys have provided to save me from going to service department.

I just replaced 2005 AVEO 5 LT spark plug with brk6eix-11, after start the car, engine shake like crazy and engine light start flashing ? Any advise why this is happening. I have to say I did not check the spark plug gap and just installed it out the box. Somehow I assumed spark plug gap is pre-set for the AVEO 5.

Is the shaking/engine light flashing happening because of the gap if that is not set properly ?

Also I didnt only changes the spark plug but I also replaced the Valve Cover Gasket, (engine oil leak) is it possible engine shaking is happening because some thing went wrong with gasket installation ?

Any help will be appreciated.
