Well, I'm in the middle of replacing my alternator. As I'm doing this, I'm thinking of upgrading the battery, and maybe plugs.

Is there a recommended battery, or a good high input one to use. My system uses a noticeable amount of power, and I'd like to have the best unit I can get to keep it all powered.

As well, for spark plugs, should I just go with the regualr stock ones, or are there good aftermarket ones to pick. There's a lot of choice out there, but I want to make sure I get the best units for my car, as well as not overpaying for junk.

Thanks for any help.

 

Optima Yellow Top

NGK ZFR5F-11 extended reach

 

Perfect, thanks a bunch.

 

What size/model of Optima does the Protege use?

 

Hold on .. let me go find out quick

 

I dunno man .. I couldn't tell from my battery tie-down. I'll tell you tomorrow when it gets light out again.

 

Sounds good. Thanks alot for the help, dont want to order the wrong part - happens often enough with me. Shops always order me P5 parts -_-

 

lol that must suck

i myself am in the market for a new battery but i'm undecided which i should really go with
but from readin' this post, i guess i should go with a yellowtop, right Krayzie?

below is the link to the thread i posted about it.

I just bought one from wal-mart, all the big boys like Consumer Reports and such has their batteries rated at the top especially for what you spend on them. Just my 2 cents though.

 

optima makes the best deep cycle battery. the RED battery is the sport compact battery however most people use the yellowtop because it's "faster"

 

i have a red top and works just fine, didn't get a yellow top because the said it wouldn't fit. but like the battery very much, lights don't dim as much anymore.

 

They lied ...

 

FWIW, I have the ngk zfr5f-11 long reach plugs installed, noticed no improvement in driveability or performance. I get some pinging when I use less than 89 octane mid-grade. I'd go with the stock ngks or densos. just my opinion.
