spark plugs
 
Hey, how do I access and remove the spark plugs in my 08 3? Im looking to install a set of those pulstar plugs. BTW, is there a group buy going on for those?

I would stay away from those plugs if I was you. I've heard some horror stories about them.

http://www.amazon.com/gp/product/B00...cm_cr_asin_lnk

Read some of the reviews. I have heard alot about them getting too hot and melting and causing issues. I wouldn't touch those plugs with a 30 ft pole in my relatively new 2006 mz3.

I was going to just get ngk laser iridium plugs (thats what they came with).

But, I had a hard time finding them ... I ended up putting autolite xp's in it. So far haven't had a problem with them.

As far as getting to your spark plugs ... they are not that hard to get too ... take the cover off of the engine....remove the coil packs using a long socket ... then take the boot out of the engine. The spark plug socket that is needed to get the spark plug out is a 5/8" plug socket. If you do change your plugs ... make sure to use anti-seize compound on the threads ... and dielectric greese in the boot. Also make sure not to get any debris in the engine (use compressed air before removing the plug.

Oh and one thing no body told me was that you have to twist off the plastic engine cover holders (they are on pretty tight) on the 2nd and 4th plug spot.

Any questions just ask ... I just changed my plugs on my 06 mz3 last weekend.

Ditto - don't waste time or money on plugs you aren't going to get that big of gain
besides the ones you got in there are good for 75,000 miles I would just leave them.

whoa -- I hadnt heard of any negativity about those plugs til now. But then I hadnt really researched them much either. Im mainly looking for efficiency improvements so Im also considering a CAI and dropping the body an inch or so. If you guys have some suggestions on what works well, Id definitely like to hear them!
Thanks for the feedback.

well I saw on this forum that they stopped selling the mazdaspeed CAI at the dealers because of water getting in the engine

I would go with the mazdaspeed suspension that you can get at the dealer if you can afford it.
