Ignition Systems for a Stock MP5

[jad0110]

Hello all, thanks ahead of time for any suggestions you can provide!

First off, I purchased my '03 red MP5 5-spd new in Jul '03. Almost 5 years later I now have 42,500 enjoyable, trouble free miles on her (headbang) !

I am looking at page 8-4 in the owners manual, and it states that the plugs should be changed every 30,000 miles. Huh? Seems a little early to me. What's everones experience with this?

Anyway...

If the plugs do need to be replaced, I figure now may be a good time to upgrade the ignition system (my warranty has expired). What I am looking for is something that is easy to install and will give a boost in both performance and mileage if at all possible. Reliability is of the utmost importance.

Thanks again for your suggestions.

EDIT: After reading other threads, is it just better to stick with the stock parts???

I stick with teh stock parts. Ive changed and had nothing but problems.

Stick with the NGK plugs v gap or what ever they are. They are cheap like $8 for the set at your local autoparts place.

Thanks for the reply. After doing more research, I concluded that using the pre-gapped plugs from the Mazda dealer at a whopping $9.50 or so is the best deal.

Um, or you could buy plugs from an auto parts store for $1.50 and get a $1.00 plug gapper. There's no reason to buy expensive plugs.

the NGK plugs at the auto parts store are pregap and are OEM Mazda i jsut check ti with my gapper to double check.

(i would double check the gap wit hteh plus from the dealer. Alot can happen in shipping)

mazda dealer = FAIL...buy good aftermarket as suggested, gap them yourself and go to the movies and have some popcor with the savings!!

always make sure they are properly gapped even though they say they are pregapped. Mine were all gapped at .35 instead of .44

RReally...
.35''...thats one hell of a spark plug gap.

I would think you would use about a .035''.....But thats just me
