what sparkplugs to get

[johnwc723]

well i have decided to get new sparkplugs and O2 sensors to maybe make my car get better than 14mpg, are iridium sparks necessary or what woudl you guys reccomend for good gas mileage/proformance

Ngk copper have worked fine for me in all my cars. I don't see why anyone would spend that much for those precious metal plugs.

I would get NGK-Rs they run about 1-2 dollars each good plugs and NTK O2 sensors I got some from www.nopionline.comI have the iridium and did feel a difference between the two but they were also about 40 dollars

[johnwc723]

looks good, crap what engine to i have, i have always wondered this but never foudn out is it the a3 or a1 being an 89 pgmfi

[johnwc723]

also there appears to be two different types of NTK sensors, one being OE and $20 more than the "universal replacement" im under the impression that i need two of them, is this worth it to get the more expensive ones?

OK you have an a20a3 engine

Second you need two sensors.

I bought the 20 dollar each ones you have to splice the connectors from the stock ones onto them it is easy just get some waterproff but splices I used red ones with the meltable soder in the middle. If you don't want to do that get the expensive ones

[carotman]

yeah but they get some carbon deposits over time... I prefer to change mine more often. Besides, when changing the plugs, you can tell if the car is lean of rich...

I just use regular honda plugs (ngk V groove)

so they are pretty much the same otherwise? i can splice stuff, or might i run into problems later down the line

Yea your check engine light will come on. or your ecu will throw you some codes.

[johnwc723]

alright orderde 4 new plugs NGK V, 2 o2 sensors, temp sending unit, pvc valve, hopefully one of those will do the trick, ill get a new thermostat too soon :)

If only they lasted 4x as long for costing 4x as much.

[nswst8]

wish they did last that long, but I believe the performance are worth it to me.
unless a different gives a equel performance for a 1/4 of the price.
Recommendations.
