00:00If you're chasing a rough idle, a stubborn diesel leak, or the dreaded injector knock on your 1.7
00:05CDTI, the seals are almost always the culprit and today I've rounded up the best deals for the top
00:105 injector seals and return pipes so you don't have to dig through endless listings.
00:14First up, the premium 4-piece set with OE number 9737-6304 and this one's the crowd
00:21favorite with nearly 4,700 sold and a solid 4.6 rating. What I like here is that you get
00:27all 4
00:27upper rubber seals in one pack, so you can do the whole job properly instead of hunting them down
00:32one at a time. At just $9.68, it's a little more than the budget options, but the peace of
00:39mind of
00:39a complete set makes it an easy pick. Next, if you want the exact OE match without paying extra,
00:45this one's for you, OEM 9737-6304, perfect fit for the Astra H&J, MK5 and MK6, Corsa D, and
00:53Maka 1.7
00:54CDTI. It's got the highest rating in this whole lineup at 4.8, and with over 4,600 sold, people
01:01clearly keep coming back. Here's the kicker, it's only $4.45, which honestly makes it the best value
01:09on this entire list. Third on the countdown is another genuine bargain, the 9737-6304 and 560-7638
01:18upper injector seal, again sitting at a 4.8 rating with around 4,600 units sold. Same reliable fitment
01:25for the Vauxhall 1.7 CDTI family, and if you cross-reference those OE numbers, you'll see it
01:31matches exactly what the dealer would hand you. At $4.76, it's basically pocket change to fix a leak
01:38that could cost you way more down the road. Coming in at number 4 is a 4-pack of upper
01:43seals for the
01:44Astra H&J, Corsa D, and Maka 1.7 CDTI, listing both 9737-6304 and 560-7638. It's rated 4
01:55.6 and has
01:56moved over 4,500 sets, which tells you it's a proven workhorse. The price sits at $6.07,
02:03a touch more than the cheapest options, but still a fraction of what a garage would charge just for
02:07the parts. And rounding out the top 5 is something a little different, a fuel pressure regulator,
02:13part number 0280-160-575, fitting everything from BMW and Audi to VW, Ford, Mercedes, Renault,
02:21and Saab. If you're chasing fluctuating rail pressure or hard starts, this is the piece
02:26that ties it all together. It's priced at $9.16 with a strong 4.8 rating and over 4,200
02:34sold,
02:34so it's clearly doing its job for a lot of people. And that's your top 5 injector seals and return
