Replacing Spark Plugs , And Spark Wires

[Yun Yomix]

I am in the process of fixing my Car, and i would like to know what would you guys recommend thats the best for my 93 KA?

Spark Plugs and Spark Wires ( or Hot wires i dunno).

Money really doesnt matter w/e makes the motor run the best it can.

Best I can get outa "Auto Zone" Thanks.

For anything but a super-modified KA, buy the cheapest plugs and wires you can get.

Plugs should be under $1 each, wires should be about $50-60 max for a set.

then get the next cheapest ones. Either way, don't spend more than $2 a plug or you're just throwing away money :)

If I've been fine running $2-2.50 plugs on two 350hp cars in a row, you'll be ok.

Matts right. I mean you might get +1mpg and +1hp from the $20 spark plugs. Nissans electrical systems have plenty o' power.

hehe...it's all about dollars per horsepower :)

Honestly, you want the best shot at cheap gains in a naturally aspirated vehicle...make yourself a set of ground wires. Don't go and buy the pre-made $150 sets, just make some from some cheap 4ga wire and lugs.

4ga jumper cables = $15 at wal-mart, should give you about 10'+ of wire to work with
4ga lugs from any electrical store = $10 for a package, you need 2 for each ground wire you make, i'd aim for 3-5 grounds depending
Time to make a "grounding kit" = an hour depending on skill level.

It's pretty likely you'll pick up a few horsepower, especially on an older car with a slightly (or very) deteriorated ground system.

Basically, you can do two routes:
1) ground the following items all back to the battery; alternator, chassis, intake manifold, block [if you can find a good bolt], transmission [if you can find a good bolt]. if you want to get real trick with this pick up a power distribution block from an electrical place. run one ground from battery negative to block, then from block out to each of the ground points
2) ground the above items individually to the chassis.

both of the above accomplish the same result; cleaner ground for the entire electrical system. since most of the engine related sensors (such as TPS, temp sensors, etc.) all ground through the chassis or the part they're screwed into (such as the coolant inlet for the CLT sensor), they'll all give off cleaner signals to the ECU. Without going into too much detail, that's a good thing :)

go with NGK spark plugs and Wires. plugs should be the proper spec (see any 240sx faq for part numbers) and ngk wiring kit. about $1 each for plugs and 40 bucks for wiring. plus NGK wiring is pimp bright blue. :)

bah i went with some shity Densos and those "Double silicone" wire sets.

i needed em fast so atozone was the place i got em at.

EDIT: damn i suck at typing

[mr peas]

i use nippon densos :D
