You don't necessarily have to buy it off Amazon but they have the best price for it. Denso is Hondas OEM manufacturer. Make sure it is the Denso 234-4099 model number. It is what it came with. Also, for spark plugs and wires, use NGK. NGK ZFR5F-11. You should be able to go to an auto parts store and get those. It shouldn't cost more than $3 a piece and you need 4. Here are the spark plug wires: http://www.amazon.com/NGK-HE76-Premium-Spark-Plug/dp/B000IY8ODS/ref=sr_1_fkmr1_1?s=automotive&ie=UTF8&qid=1380741594&sr=1-1-fkmr1&ymm=1998%3Ahonda%3Acivic&keywords=1998+honda+civic+dx+spark+plug+wires
As for tools, you'll need a 7/8" offset o2 sensor socket and a breaker bar because it will be on tight! For the spark plugs, you'll need a 5/8 spark plug socket with a rubber piece or a magnet inside to grip the spark plug. the wires won't require tools but you'll need a bit of dielectric grease to prevent the elements from getting to the connections.
I recommend you use this spark plug socket. It's treated me really well and is very durable: http://www.amazon.com/GearWrench-80546-8-Inch-6-Inch-Swivel/dp/B0014ZVSVK/ref=sr_1_1?s=automotive&ie=UTF8&qid=1380741751&sr=1-1&keywords=spark+plug+tool Also, it won't hurt if you go and buy a 3/8" 6" extension for your 3/8" ratchet.
Also posted the wrong link I wanted this brand. TIA
