Ok - First of All sorry for asking this but I tried the Search and nothing.

What Spark Plugs Do I need to get for my 98 Eclispe Spyder GS (Non-Turbo 2.4L SOHC 16-Valve Engine - 4G64 Engine). Is it the

NGK SPARK PLUG: BKR6EVX-11

Our Price $2.50

My Spyder recently started to sputter when I first start it up. The
RPM goes from 900-500 back and forth but never dies.

But the weird thing is that it runs fine at all speed. Only when I'm
at a red light it starts to sputter up and down.....

My check engine light came on about a month ago and I'm pretty sure
it's the Front O2 Sensor because I was getting poor gas mileage but
the engine was running fine (Wasn't sputtering at all) The CEL came
on after I washed the engine if that makes a difference but I think
it's the Front 02 - Well I hope cuz I just bought a new one from
www.machv.com for $79 buck.

I'm going to install it next week along with my new Greddy Evo
exhaust - Yes Finally got one after a month on back order.

So the only thing I think could cause this sputtering is the Spark
plugs. I'm running AC Delco Rapid Fire #5. Their only 3 months old
and look fine but I thought I try something different.

So please tell me what spark plugs to get. I need the exact Model
Number please.

I figure just get the same heat range as stock cuz the only thing I
have on my car for performance is:

1) Magnecor 8.5mm Spark Plug Wires
2) Hiper (K&N) Air intake system
3) Greddy Evolution Exhaust for GS/RS (60mm pipe - 2.5")

Please advice and educate me wise one.

Thanks,
Mike
