Hey guys!.
I think its time for me to change the spark plugs because they have not been changed for a while. Also, is there a sign when they need to be replaced?
Can I just get non-NGK platinum spark plugs or do I have to get NGK ones since they are really expensive at $16.00.

One more question, I do not want to get cone filters, but still should I get the flat K&N filter? What are your recommendations?

 

Just get NGK V-Power coppers. $1.89 each.

 

I'f you've never changed your plugs than change them! Get NGK Platinums #PFR5G-11 from Courtesy Parts.com, 6 pack for $57.00.
For the air filter, get an Amsoil EaA74 panel filter (absolute efficiency)
cleaning is every 25k, and lasts 4 years.

 

you can get the NGK coppers and they are just as good as the plats just last half as long. But for ~$1.20 a plug much cheaper. K&N panel drop in will do a good job.

 

Here's some good reading on the K&N filter:

Even in dusty as.s desert climates




How long is a 'while'? And what's in there now?

OEM air filter, 5-6$... No complaints.

 

Just blow out the dust at every oil change! As for desert climates, it's not made for offroad!!! (amsoil.com)EaA74

 

How much does that filter cost?

 

Got from Talkinghorse/GD. I paid total 28.74 (26.00), the distribution center is 5 mins. from my house.
