Product Details

The Bosch YR7DC+ (also known as Bosch 79027 / 0242135515) is a heavy-duty copper-core spark plug featuring a yttrium-enhanced nickel center electrode, engineered to deliver up to 50% longer service life compared to standard copper plugs.

Easy site to order

Good job

Your site is awesome.

Easy

Exactly what I needed and was very affordable and delivered to my house in only a few days.

A+

Item was exactly as described and was delivered on time Friday after ordering it on Wednesday. Great job! Thanks.

quick and easy

I was looking for a part for my Mallory distributor at a fair price. I called around to my local speed shops and they all had to order the part, so I went on line. With a little research for the best price here, at Autoplicity. I ordered the part last night and it has shipped 24 hours later. I like that. I have bookmarked Autoplicity so I can use the again. Thanks guys.<br><br>Jim

easy, fast

Had the hard to find part I was looking for in stock. Ordered it late saturday night, first thing monday morning it was shipped out! Couldnt of asked for more!

Autoplicity had the best price and was easy to order and use. My items were shipped promptly!

Not pleased when I got an error when paying with credit card.

I only gave them a 3 star raring on their shipping because I went on their site on Tuesday and the order said it had not been shipped. On Wednesday I received my shipment. The left hand needs to figure out what the right hand is doing. Other than that, GREAT

I couldn't find this in stock anywhere! Not only did Autoplicity have it in stock they were about $10 cheaper than any other sites list price. Received the package very fast! Will use Autoplicity for all of my part needs!

They had exactly what I needed and the cheapest price i found anywhere.
